Order 20288.
266 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #23778868 | C2 | direct (N × H) |
| 2. C2×#19099584 | C2 | semidirect |
| 3. C2×D317⋊C8 | C2 | semidirect |
| 5. #19099584 | C22 | semidirect |
| 6. D317⋊C8 | C22 | semidirect |
| 29. C2×C317 | #131 | semidirect |
| 32. C317 | C2×#131 | semidirect |
| 63. C2 | #23778868 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
