Order 1728.
494 conjugacy classes of subgroups.
The subgroup lattice has 306 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 171. C3×C9 | #400 | semidirect |
| 258. C9 | #4985 | semidirect |
| 298. C3 | #10588339 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
