Order 22784.
1094 conjugacy classes of subgroups.
The subgroup lattice has 470 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |

| 106. C22⋊Dic89 | C2×Q8 | semidirect |
| 242. C89 | #25853 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
