Order 20224.
1082 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 |
|---|---|---|
| 3. #23764750 | C2 | semidirect |
| 4. #23764745 | C2 | semidirect |
| 30. C2×#11929608 | Q8 | semidirect |
| 64. C2×C42×C79 | Q8 | semidirect |
| 171. C79 | #23560 | semidirect |
| 225. C2×C42 | Dic158 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
