Order 400.
51 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C2×C4×C25 | C2 | semidirect |
| 3. C2×Dic25 | C2 | semidirect |
| 7. C2×D25 | C4 | semidirect |
| 18. C25 | C22⋊C4 | semidirect |
| 32. C2×C4 | D25 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
| subgroup | index |
