Order 20224.
1390 conjugacy classes of subgroups.
The subgroup lattice has 344 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #23771964 | C2 | semidirect |
| 3. #23763396 | C2 | semidirect |
| 4. #23763392 | C2 | semidirect |
| 5. C2×#19098332 | C2 | semidirect |
| 178. C79 | #20640 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
