Order 720.
66 conjugacy classes of subgroups.
| subgroup | G/H | |
|---|---|---|
| center, Frattini, hypercenter | C2 | D3×A5 |
| commutator, hypocenter | C3×SL(2,𝔽5) | C2 |
| Fitting, socle, cosocle | C2×C3 | C2×A5 |
| LCS | G ▷ C3×SL(2,𝔽5) | |
| UCS | C1 ◁ C2 | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C3×SL(2,𝔽5) | C2 | semidirect |
| 5. SL(2,𝔽5) | D3 | direct (N × H) |
| 49. D3 | SL(2,𝔽5) | direct (N × H) |
| 56. C3 | C2×SL(2,𝔽5) | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
