Order 1600.
92 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C5×Dic40 | C2 | semidirect |
| 3. C5×#3926 | C2 | semidirect |
| 8. #64740 | C5 | direct (N × H) |
| 16. Dic40 | C2×C5 | semidirect |
| 18. #3926 | C2×C5 | semidirect |
| 44. C52 | SD64 | semidirect |
| 66. C5 | #64740 | direct (N × H) |
| 67. C5 | C5×SD64 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
