Order 15616.
690 conjugacy classes of subgroups.
The subgroup lattice has 436 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #21460688 | C2 | direct (N × H) |
| 215. C2×C61 | #1292 | semidirect |
| 245. C61 | C2×#1292 | semidirect |
| 431. C2 | #21460688 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
