Order 15616.
918 conjugacy classes of subgroups.
The subgroup lattice has 420 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. #16839634 | C4 | semidirect |
| 102. C22⋊Dic61 | C4⋊C4 | semidirect |
| 228. C61 | #11205 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
