Delta is most compatible with Gamma, then Alpha, then Beta (with beta, there isn't any compatibility).

Gamma is most compatible with Delta, then Beta, then Alpha (with alpha, there isn't any compatibility).

Beta is most compatible with Alpha, then Gamma, then Delta (with delta, there isn't any compatibility).

Alpha is most compatible with Beta, then Delta, then Gamma (with gamma, there isn't any compatibility).

So for an INTp:

1. ESFp
2. INTp
3. ISFj
4. ENTj

5. ENFp, ISTp, INFj
8. ESTj

9. INFp, ESTp, ISTj
12. ENFj

13. INTj, ENTp, ISFp
16. ESFj

(some types are on the same level, because I couldn't figure out how to order them.)

Is it just me, or does this not make perfect sense?
