Order 20224.
354 conjugacy classes of subgroups.
The subgroup lattice has 200 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 12. #500×C79 | C4 | semidirect |
| 14. #499×C79 | C4 | semidirect |
| 21. #14579101 | Q8 | semidirect |
| 104. C79 | #13288 | semidirect |
| 107. #500 | Dic79 | semidirect |
| 109. #499 | Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
