Order 1200.
72 conjugacy classes of subgroups.
| subgroup | G/H | |
|---|---|---|
| center, Fitting, hypercenter | C2×C5 | S5 |
| commutator, hypocenter | A5 | C4×C5 |
| Frattini | C2 | C5×S5 |
| socle, prime radical | C2×C5×A5 | C2 |
| cosocle | C2×A5 | C2×C5 |
| LCS | G ▷ A5 | |
| UCS | C1 ◁ C2×C5 | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C5×A5 | C4 | semidirect |
| 4. A5⋊C4 | C5 | direct (N × H) |
| 14. A5 | C4×C5 | semidirect |
| 59. C5 | A5⋊C4 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
