Order 15616.
588 conjugacy classes of subgroups.
The subgroup lattice has 338 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 7. #16839632 | C4 | semidirect |
| 8. #16839632 | C4 | semidirect |
| 13. C4×C4⋊Dic61 | C4 | semidirect |
| 188. C61 | #8716 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
