Order 20224.
774 conjugacy classes of subgroups.
The subgroup lattice has 282 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. #19098965 | C4 | semidirect |
| 134. Dic79 | #499 | semidirect |
| 150. C79 | C4×#499 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
