Order 20224.
914 conjugacy classes of subgroups.
The subgroup lattice has 306 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 13. C4×Dic316 | C4 | semidirect |
| 72. Dic316 | C4⋊C4 | semidirect |
| 139. C4×C79 | #441 | semidirect |
| 161. C79 | #22674 | semidirect |
| 295. C4 | #19098669 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
