Order 20224.
1050 conjugacy classes of subgroups.
The subgroup lattice has 528 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 15. C2×#14579161 | C4 | semidirect |
| 16. C2×#14579161 | C4 | semidirect |
| 17. C2×#14579153 | C4 | semidirect |
| 20. C2×C4×Dic158 | C4 | semidirect |
| 21. C2×C4×Dic158 | C4 | semidirect |
| 270. C79 | #21826 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
