There are 18 type+wing combinations and there are 27 tritypes. Some combinations can have all three numbers of one of the centers. Obviously, all 369 Chameleons can do that regardless of their wing if they access wings. It is one of the main things that sets them apart from all the other types. But there are a handful of non-chameleons who do that, too.
1 is the heart-ish gut type. 8 is the mind-ish gut type.
Triple Heart
- 1w2: 1 has an arrow to 4. With a 2 wing and 3 in the tritype, 1 can get 234.
- 2w3: has an arrow to 4. With a 3 wing, 2 can have 234.
- 4w3: has an arrow to 2. With a 3 wing, 4 can have 234.
- 3 can access both wings to get 234.
Triple Mind
- 5w6: 5 has an arrow to 7. With a 6 wing, 5 can have 567.
- 7w6: 7 has an arrow to 5. With a 6 wing, 7 can have 567.
- 8w7: 8 has an arrow to 5. With a 6 in the tritype and a 7 wing, 8 can get 567.
- 6 can access both wings to get 567.
Triple Gut
- 2w1: 2 has an arrow to 8. With a 1 wing and with 9 in the tritype 2 has access to 891.
- 7w8: 7 has an arrow to 1. With a 8 wing and with 9 in the tritype, 7 can have access to 891.
- 9 can access both wings to get 891.
Note that 9 can and often does access both wings but, for whatever reason, it is considerably harder and takes a great deal more maturity and emotional health for for a 3 or a 6 to access both wings.
