Order 1152.
636 conjugacy classes of subgroups.
The subgroup lattice has 261 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #10588206 | C2 | semidirect |
| 8. C9×#117 | C4 | semidirect |
| 14. #63488 | C4 | semidirect |
| 19. C22×C9⋊C8 | C4 | semidirect |
| 137. #117 | Dic9 | semidirect |
| 210. C9 | #1735 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
