Order 18688.
686 conjugacy classes of subgroups.
The subgroup lattice has 264 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 42. C4×#10596831 | Q8 | semidirect |
| 140. C73 | #21341 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
