Order 15616.
1630 conjugacy classes of subgroups.
The subgroup lattice has 300 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 10. C2×#14519777 | C4 | semidirect |
| 38. C2×C4×Dic61 | Q8 | semidirect |
| 172. C61 | #14282 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
