Order 20224.
734 conjugacy classes of subgroups.
The subgroup lattice has 274 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 10. C8×Dic158 | C4 | semidirect |
| 145. C79 | #22739 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
