Order 1280.
658 conjugacy classes of subgroups.
The subgroup lattice has 268 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #10598203 | C2 | direct (N × H) |
| 207. C2×C5 | #1309 | semidirect |
| 243. C5 | C2×#1309 | semidirect |
| 264. C2 | #10598203 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
