Order 17728.
190 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C2×#17984572 | C2 | semidirect |
| 2. C22⋊#14555667 | C2 | semidirect |
| 5. C2×#14555667 | C22 | semidirect |
| 29. C22×C277 | M16 | semidirect |
| 38. C277 | #407 | semidirect |
| 68. C22 | #17984572 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
