Order 15616.
1662 conjugacy classes of subgroups.
The subgroup lattice has 242 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 15. C2×#125×C61 | C4 | semidirect |
| 97. C2×Dic61 | #125 | semidirect |
| 128. C2×#125 | Dic61 | semidirect |
| 139. C61 | #14709 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
