Order 1280.
638 conjugacy classes of subgroups.
The subgroup lattice has 280 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. #10599382 | C2 | direct (N × H) |
| 228. C2×C5 | #1676 | semidirect |
| 259. C5 | C2×#1676 | semidirect |
| 275. C2 | #10599382 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
