Order 15616.
342 conjugacy classes of subgroups.
The subgroup lattice has 232 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #21443797 | C2 | semidirect |
| 51. C2×Dic122 | C16 | semidirect |
| 135. C61 | #11637 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
