Order 20224.
822 conjugacy classes of subgroups.
The subgroup lattice has 290 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 |
| 92. C42×C79 | Q16 | semidirect |
| 153. C79 | #21276 | semidirect |
| 237. C42 | Dic316 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
