Order 20224.
1138 conjugacy classes of subgroups.
The subgroup lattice has 482 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. C2×#14579084 | C4 | semidirect |
| 13. #19098469 | C4 | semidirect |
| 80. C2×Dic158 | C42 | semidirect |
| 165. C2×C4×C79 | #103 | semidirect |
| 246. C79 | #10932 | semidirect |
| 420. C2×C4 | #14579084 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
