Order 15616.
998 conjugacy classes of subgroups.
The subgroup lattice has 330 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #21447378 | C2 | direct (N × H) |
| 163. C2×C61 | #2099 | semidirect |
| 187. C61 | C2×#2099 | semidirect |
| 321. C2 | #21447378 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
