Order 31712.
76 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C4⋊Dic991 | C2 | semidirect |
| 3. C4×Dic991 | C2 | semidirect |
| 7. C2×C4×C991 | C4 | semidirect |
| 19. C991 | #117 | semidirect |
| 27. C2×C4 | Dic991 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
