Order 20288.
142 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 5. C22⋊#11929639 | C4 | semidirect |
| 7. C22×Dic317 | C4 | semidirect |
| 9. C22×C4×C317 | C4 | semidirect |
| 46. C317 | #342 | semidirect |
| 53. C22×C4 | #11929639 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
