Order 22784.
3158 conjugacy classes of subgroups.
The subgroup lattice has 360 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |

| 44. C4×Dic178 | C2×C4 | semidirect |
| 75. C2×Dic178 | C4⋊C4 | semidirect |
| 154. Dic178 | C2×C4⋊C4 | semidirect |
| 174. C2×C89 | #2351 | semidirect |
| 189. C89 | C2×#2351 | semidirect |
| 353. C2 | #26023169 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
