Order 20224.
866 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 |
|---|---|---|
| 3. #23763277 | C2 | semidirect |
| 4. #23763259 | C2 | semidirect |
| 7. #19098620 | C4 | semidirect |
| 23. #423×C79 | C4 | semidirect |
| 145. C79 | #20551 | semidirect |
| 149. #423 | Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
