Order 18688.
1142 conjugacy classes of subgroups.
The subgroup lattice has 278 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. C2×#14556590 | C4 | semidirect |
| 9. C2×#14556582 | C4 | semidirect |
| 42. #117×C73 | Q8 | semidirect |
| 144. C73 | #21334 | semidirect |
| 170. #117 | Dic146 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
