Order 20224.
770 conjugacy classes of subgroups.
The subgroup lattice has 296 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. C4×Dic316 | C4 | semidirect |
| 156. C79 | #22814 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
