Order 15616.
394 conjugacy classes of subgroups.
The subgroup lattice has 204 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 13. C61×#500 | C4 | semidirect |
| 16. C61×#498 | C4 | semidirect |
| 107. #500 | Dic61 | semidirect |
| 110. #498 | Dic61 | semidirect |
| 121. C61 | #9755 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
