Order 1728.
572 conjugacy classes of subgroups.
The subgroup lattice has 214 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 36. C3⋊#564 | C9 | direct (N × H) |
| 141. C3×C9 | #564 | semidirect |
| 190. C9 | C3⋊#564 | direct (N × H) |
| 209. C3 | C9×#564 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
