You are a Type 7 with a 6 wing: "The Entertainer" 
Your trifix is 7w6, 2w3, 8w7. 
In enneagram theory, you have one type for how you relate to the world (either 8, 9, or 1), one type for how you think (5, 6, 7) and one type for how you see yourself (2, 3, 4.) Your tri-fix contains one number from each of these triads. They are listed in the order of how strongly they present in your personality. 
Your core type (your strongest type) is Type 7 with a 6 wing: Type Seven individuals are energetic, engaging, and playful. They have a love for life and can easily jump from one exciting topic to the next. The Type Seven thought process is a bit scattered, but thats because they are easily interested in many different things. This is why Type Seven is often called The Enthusiast. When in a growth state, Type Sevens become focused like Type Fives. When theyre stressed, they become a perfectionist like a Type One. The enthusiastic nature of the Type Seven combines with the cooperative nature of the Type Six, making the 7w6 a very outgoing type. 
Your second type (your next strongest type) is Type 2 with a 3 wing: Type Two individuals are generous and kind. Twos love others and want to be loved, and becoming close to others is a theme in the life of the Two. This is why Two is often referred to as the Helper type  because they keep coming, time and time again, to the aid of others. Out of all the types in the Enneagram, Twos are the most likely to help someone when theyre feeling down or when theyre being attacked. When a Type Two is stressed, they can become aggressive like an unhealthy Type Eight. When theyre healthy, a Type Two becomes emotionally aware like a healthy Type Four. You are a Type Two with a Three wing, which means that the helpful nature of the Two combines with the ambitious nature of the Three, making you a very driven individual. 
Your third type (the least-used of the three) is Type 8 with a 7 wing: Eights are assertive, dominant individuals who naturally take control of situations. Eights are aggressive in satisfying their needs, and indeed, Type Eight is the most aggressive personality type in the Enneagram. When in a state of growth, Eights become like Type Twos - caring and protective of other people. When Eights are stressed, they become withdrawn and secretive like Type Fives. You're an Eight with a Seven wing, which means that the outgoing nature of Seven combines with the assertive nature of Type Eight to create one of the most dynamic types in the Enneagram. Type 8w7s are a force to be reckoned with.
