Order 15616.
616 conjugacy classes of subgroups.
The subgroup lattice has 322 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 16. C61×#400 | C4 | semidirect |
| 171. #400 | Dic61 | semidirect |
| 180. C61 | #9023 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
