Order 1728.
526 conjugacy classes of subgroups.
The subgroup lattice has 284 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #11720298 | C2 | semidirect |
| 11. C2×C9×Dic6 | C4 | semidirect |
| 129. C2×Dic6 | Dic9 | semidirect |
| 171. C3×C9 | #419 | semidirect |
| 247. C9 | #5120 | semidirect |
| 278. C3 | #10588906 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
