Order 20224.
1502 conjugacy classes of subgroups.
The subgroup lattice has 300 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×#19098589 | C2 | semidirect |
| 4. #23763583 | C2 | semidirect |
| 5. #23763096 | C2 | semidirect |
| 11. C2×Dic79⋊C8 | C22 | semidirect |
| 18. #19098317 | C22 | semidirect |
| 156. C79 | #20835 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
