Tritypes, and/or Trifixes. Sometimes these words are used interchangeably, but by technicality there are some differences. They have a few things in common however, they both consist of 3 enneagram types, each from a different quadrant, these two additional add ons are often referred to as fixes.
Tritype uses these three fixes/types in a stacking order of influence, and uses all of the core passions and fears of each type, while Trifix only uses the fixations as a way to influence. This is also why Tritype follows a linear pattern when displaying a type. It goes to the number next in line (Ex. A core 8 with a 7 fix, in order of dominance/influence, and a 2 fix would look like 827 in Tritype, but 872 in Trifix - However both begin with your core Enneagram type).
Your Tritype is based on three different core functions, Heart, Head, and Gut. Heart fixes are E2, E3, and E4. Head fixes are E5, E6, and E7. Gut fixes are E8, E9, and E1. The order of which these go in (ie. 425, 853, etc) is based on your core enneagram. For example, if you are a 4w5, the first number of your tritype will be 4. Depending on which function it is (Heart, Head, or Gut), the orders will be different. The order of the fixes is as follows:
Gut - heart - head
Heart - head - gut
Head - gut - heart
