Order 15616.
518 conjugacy classes of subgroups.
The subgroup lattice has 336 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C2×#16839544 | C2 | semidirect |
| 2. #21443757 | C2 | direct (N × H) |
| 6. #16839544 | C22 | semidirect |
| 169. C2×C61 | #1321 | semidirect |
| 181. C61 | C2×#1321 | semidirect |
| 333. C2 | #21443757 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
