Order 20224.
1378 conjugacy classes of subgroups.
The subgroup lattice has 278 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C2×#19098616 | C2 | semidirect |
| 2. #23763471 | C2 | semidirect |
| 3. #23763384 | C2 | semidirect |
| 5. C4×C22⋊(C79⋊C8) | C2 | semidirect |
| 145. C79 | #20718 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
