Order 640.
152 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C5×#499 | C2 | semidirect |
| 3. #64711 | C2 | semidirect |
| 4. #64681 | C2 | semidirect |
| 24. #499 | D5 | semidirect |
| 74. C5 | #2244 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
