Order 18688.
586 conjugacy classes of subgroups.
The subgroup lattice has 270 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #22624979 | C2 | semidirect |
| 3. #22624978 | C2 | semidirect |
| 7. #17989643 | C4 | semidirect |
| 139. C73 | #12551 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
