Order 15616.
1134 conjugacy classes of subgroups.
The subgroup lattice has 360 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #21445961 | C2 | direct (N × H) |
| 36. C2×C4×Dic61 | C8 | semidirect |
| 100. C4×Dic61 | C2×C8 | semidirect |
| 178. C2×C61 | #1839 | semidirect |
| 201. C61 | C2×#1839 | semidirect |
| 351. C2 | #21445961 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
