Order 1728.
770 conjugacy classes of subgroups.
The subgroup lattice has 372 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 18. #88534 | C4 | semidirect |
| 213. C3×C9 | #387 | semidirect |
| 311. C9 | #4652 | semidirect |
| 362. C3 | #10588332 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
