| subgroup | G/H | |
|---|---|---|
| center | C2×C4×C491 | D4 |
| commutator | C4 | C2×C8×C491 |
| Frattini, cosocle | C42 | C22×C491 |
| socle, prime radical | C22×C491 | C4⋊C4 |
| LCS | G ▷ C4 ▷ C2 ▷ C1 | |
| UCS | C1 ◁ C2×C4×C491 ◁ C42×C491 ◁ G | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 12. C8×C491 | C8 | semidirect |
| 22. C491 | #335 | direct (N × H) |
| 23. #335 | C491 | direct (N × H) |
| 35. C8 | C8×C491 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
