Order 20288.
70 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. C4×Dic317 | C4 | semidirect |
| 7. C2×Q8×C317 | C4 | semidirect |
| 25. C317 | #354 | semidirect |
| 29. C2×Q8 | #11929639 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
