Order 20224.
888 conjugacy classes of subgroups.
The subgroup lattice has 420 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #23774553 | C2 | semidirect |
| 4. #23762444 | C2 | semidirect |
| 6. #23761965 | C2 | semidirect |
| 217. C79 | #18311 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
