Order 15616.
654 conjugacy classes of subgroups.
The subgroup lattice has 302 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. #16839815 | C4 | semidirect |
| 11. #16839628 | C4 | semidirect |
| 14. C4×C4⋊Dic61 | C4 | semidirect |
| 19. C61×#383 | C4 | semidirect |
| 163. #383 | Dic61 | semidirect |
| 173. C61 | #8025 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
