Order 20224.
1782 conjugacy classes of subgroups.
The subgroup lattice has 254 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #23761668 | C2 | semidirect |
| 4. #23761630 | C2 | semidirect |
| 13. C2×#117×C79 | C4 | semidirect |
| 132. C79 | #14343 | semidirect |
| 135. C2×#117 | Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
