Order 33777.
480 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #26014628 | C3 | direct (N × H) |
| 2. C3×#16836730 | C3 | semidirect |
| 3. C32×C139⋊C9 | C3 | semidirect |
| 5. #16836730 | C32 | semidirect |
| 8. C3×C139⋊C9 | C32 | semidirect |
| 17. C3×C139 | #737 | semidirect |
| 20. C139 | C3×#737 | semidirect |
| 37. C3 | #26014628 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
