Order 15616.
814 conjugacy classes of subgroups.
The subgroup lattice has 388 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 17. C61×#340 | C4 | semidirect |
| 209. #340 | Dic61 | semidirect |
| 211. C61 | #11257 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
