Order 1728.
570 conjugacy classes of subgroups.
The subgroup lattice has 312 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 13. C4×C3⋊Dic9 | C4 | semidirect |
| 174. C3×C9 | #382 | semidirect |
| 263. C9 | #4650 | semidirect |
| 304. C3 | #10588330 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
