4w6? That's impossible, Kiddo. Here's something I posted earlier on this matter:Of course, your 4w6 sp/so/sx reading is completely fubar.
(You can't have a wing that isn't next to your main, and what is the point of putting sp/so/sx down? If all your variants are the same strength, then there is no way to distinguish a variant.)
Note: I would probably guess straight Four with an sp/so variant... but that is only a hunch on my part, I could not tell you with more certainty without spending time with you.
I think this site explains it best: How the Enneagram Personality System Works
But here's my understanding:
Okay, the Enneagram is a complex 9 archetype system. You have one core type which is the basis of your personality. Each type also has "wings," which add another dimension to your personality. Your wing must be one of the numbers adjacent to your core type. A 4 can have either a 3 or a 5 wing. A 2 can have either a 1 or a 3 wing.
Another part of the theory is integration/disintegration. Under stress, a type can "disintegerate" and behave like another type. The direction of disintegration is:
This means that a 1 under stress acts like a 4, a 4 under stress acts like a 2, and so on. Note that 9,6, and 3 have their own continuum on this scale that operates the same way. A 9 under stress acts like a 6, a 6 under stress acts like a 3, and so on.
The direction of integration is the direction in which a type grows toward healthier behaviors. It's the opposite of the direction of disintegration.
This means that a healthy 1 will begin to act more like a 7, a healthy 7 will begin to act more like a 5, and so on.
About instinctual stacks:
You have Social (SO), Sexual (SX), and Self-Preservation (SP) Instincts. They can be stacked in the six following ways:
Note that normally only the first two stronger instincts are noted, because it is assumed that that the instinct not shown is automatically the weakest instinct of the three. However, if all three are listed, the last instinct is weakest. A better explanation/description can be found here.
