Order 15616.
462 conjugacy classes of subgroups.
The subgroup lattice has 250 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 18. C61×#494 | C4 | semidirect |
| 135. #494 | Dic61 | semidirect |
| 144. C61 | #13262 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
