| LCS | G ▷ C4 ▷ C2 ▷ C1 | |
| UCS | C1 ◁ C2×C8×C251 ◁ C4×C8×C251 ◁ G | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 20. C8×C251 | C16 | semidirect |
| 31. C251 | #1367 | direct (N × H) |
| 32. #1367 | C251 | direct (N × H) |
| 52. C8 | C16×C251 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
