The socion (all 16 types) breaks up into four quadras of four types apiece. Each quadra consists of two dual pairs and contains the same four intertype relations — identity, duality, activation, and mirror. Each type within a quadra has the same four information elements in its ego and super-id blocks. This means that people from the same quadra share many of the same unspoken values. They can let down their guard around each other and be themselves without worrying that others will think poorly of them.
Individuals of the same quadra strive for a world where their four leading information elements are brought to the forefront and given the greatest freedom of expression while the other four are subdued and made to serve the leading four.
Informal small groups — such as friends that do something together regularly — tend to gravitate around a certain quadra that the greatest number of group members belong to. It is common to have "stragglers" — one or more people from other quadras that come along because they share a common interest and are willing to be a bit peripheral.
In the chart below, the order of elements is not significant. Note that all adjacent quadras share two dominant elements, while opposing quadras (1 and 3; 2 and 4) share no dominant elements. Click on the links to read descriptions of each quadra below.

The descriptions below are meant to hold true for all types within the quadra, not just those that have the elements shown as their first or second function. The phrase "X blocked with Y" means that two elements are always found in the same block of the socionic model of the psyche, implying that these aspects of reality are interconnected in the given quadra.
1. Alpha Quadra [top]
extraverted intuition blocked with introverted logic:
Types from the Alpha Quadra enjoy freely exchanging new ideas and theories as a form of intellectual leisure. They like to systematize knowledge and create new categories and speculative hypotheses without necessarily intending to see their theories tested or implemented (subdued extraverted logic).
extraverted ethics blocked with introverted sensing:
This quadra enjoys carefree emotional expression and sensory delights and is able to derive never-ending pleasure from simple things — funny stories, exotic dishes, family picnics and group outings, and visual and performing arts.
Subdued elements:
The Alpha Quadra is especially sensitive to and critical of mercantilistic views, ostentatious displays of wealth and status symbols, rude and aggressive behavior, moral criticism, and people who suggest they are wasting their time on unproductive things.
Typical Alpha quadra group behavior:
Spontaneous, disorganized activities "for the fun of it." Light-hearted, non-serious atmosphere with very few "heavy" moments. Skipping from topic to topic without focusing on the implementation of conclusions reached.
2. Beta Quadra [top]
extraverted ethics blocked with introverted intuition:
This quadra encourages dramatic self-expression with elements of theatricism and melodrama. They enjoy finding artistic means to express romantic, abstract ideals and feelings.
extraverted sensing blocked with introverted logic:
Types from the Beta Quadra are drawn to hierarchical structures that increase their personal power. They like to see convictions and beliefs materialized physically in the real world. They are often starkly blunt in their views and like "strong" humor.
Subdued elements:
The Beta Quadra is especially sensitive to and critical of earthiness, pronounced pragmatism, emotional indifference, and people who analyze their psychology and motives behind their backs.
Typical Beta quadra group behavior:
Lengthy, theatrical monologues. Loud, hearty laughter. Importance given to group rituals such as those related to food and drink. Displays of great generosity and inclusion, but with the demand of emotional involvement in group. Rowdiness. Generally theatrical atmosphere, but with periodic moments of "dead seriousness."
3. Gamma Quadra [top]
extraverted sensing blocked with introverted ethics:
Types from the Gamma Quadra have a realistic, materialistic outlook on life, relationships, and society and tend to view life as a marketplace where forcefulness, positive thinking, social maneuvering, hustle and bustle, and direct humor get you where you need to go.
extraverted logic blocked with introverted intuition:
This quadra believes that ideas and fortuitous events should be turned into something profitable and marketable — something that does some kind of work for people. The Gamma Quadra values self-sacrifice in the name of serving society.
Subdued elements:
The Gamma Quadra looks down on indulging in self-centered pleasures and in engaging in activities unrelated to society's needs.
Typical Gamma quadra group behavior:
Trading jokes on materialistic topics (money, sex, winning and losing). Rowdiness and drivenness. Prefer socializing in smaller groups (about six people or less) and planning and carrying out productive activities together.
4. Delta Quadra [top]
extraverted logic blocked with introverted sensing:
Types from the Delta Quadra value pragmatism, hard work, beautifully functional items, and earthy humor and enjoy "productive" relationships where people do projects together. They are usually emotionally subdued and like to discuss topics seriously with the intention of implementing their conclusions.
extraverted intuition blocked with introverted ethics:
Types of this quadra enjoy discussing people, internal motivation, and self-development. They believe in peaceful self-government without coercion and in the inherent potential of each human being for personal fulfillment.
Subdued elements:
The Delta Quadra doesn't appreciate high ideals or abstractions that don't relate well to real life. They also don't like large institutions or power systems that do not take into consideration the interests of separate individuals.
Typical Delta quadra group behavior:
Discussion of interesting facts about people and places. Enjoy group outdoor activities. "Live and let live" attitude. Engage only in "productive" activities and discussions. Prefer smaller groups. Emotionally subdued; generally serious, but with periodic funny moments.
So TL;DR, there are four types each that have a respective combination of 4 functions (4 types have Se, Ni, Te and Fi all together in this specific combination) and each 4-type "grouping" based on functions is a Quadra.
As mentioned in Alea's thread here, certain societies are in theory dominated by cultures based on the functions of one specific quadra. Same thing could apply for websites and I want your opinion on the Quadra fixation of TypeC.
