Order 648.
71 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C32×SL(2,𝔽3) | C3 | semidirect |
| 2. Q8×H(3,𝔽3) | C3 | semidirect |
| 3. #6204 | C3 | semidirect |
| 19. H(3,𝔽3) | SL(2,𝔽3) | semidirect |
| 37. Q8 | AΣL(1,𝔽27) | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
