Order 20224.
914 conjugacy classes of subgroups.
The subgroup lattice has 272 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. C8×Dic158 | C4 | semidirect |
| 112. Dic158 | #97 | semidirect |
| 144. C79 | #20572 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
