Order 15616.
418 conjugacy classes of subgroups.
The subgroup lattice has 258 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 15. C61×#446 | C4 | semidirect |
| 136. #446 | Dic61 | semidirect |
| 148. C61 | #8655 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
