Order 1728.
670 conjugacy classes of subgroups.
The subgroup lattice has 366 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 208. C3×C9 | #400 | semidirect |
| 305. C9 | #4658 | semidirect |
| 356. C3 | #10588338 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
