Order 20224.
874 conjugacy classes of subgroups.
The subgroup lattice has 328 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. Q8×Dic158 | C4 | semidirect |
| 9. #19099292 | C4 | semidirect |
| 171. C79 | #17632 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
