Order 20288.
146 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #23778835 | C2 | direct (N × H) |
| 4. C2×#14579268 | C4 | semidirect |
| 11. #14579268 | C2×C4 | semidirect |
| 28. C2×C317 | #97 | semidirect |
| 32. C317 | C2×#97 | semidirect |
| 61. C2 | #23778835 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
