Order 22784.
822 conjugacy classes of subgroups.
The subgroup lattice has 290 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |

| 11. C4×Dic356 | C4 | semidirect |
| 81. C4×Dic89 | Q16 | semidirect |
| 153. C89 | #21276 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
