Order 22784.
1710 conjugacy classes of subgroups.
The subgroup lattice has 366 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. C2×C4×Dic178 | C4 | semidirect |
| 55. C2×C4⋊C4×C89 | Q8 | semidirect |
| 190. C89 | #13925 | semidirect |
| 231. C2×C4⋊C4 | Dic178 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
