Order 15616.
1310 conjugacy classes of subgroups.
The subgroup lattice has 380 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 21. C61×#391 | C4 | semidirect |
| 65. C2×Q8×C61 | C4⋊C4 | semidirect |
| 203. #391 | Dic61 | semidirect |
| 212. C61 | #14501 | semidirect |
| 255. C2×Q8 | C4⋊Dic61 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
