Order 20288.
258 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C2×#19099564 | C2 | direct (N × H) |
| 8. #19099564 | C22 | direct (N × H) |
| 24. C22×C317 | Q16 | semidirect |
| 30. C2×C317 | C2×Q16 | semidirect |
| 32. C317 | C22×Q16 | semidirect |
| 57. C22 | #19099564 | direct (N × H) |
| 63. C2 | C2×#19099564 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
