Order 22784.
1878 conjugacy classes of subgroups.
The subgroup lattice has 338 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #26020336 | C2 | direct (N × H) |
| 4. C2×#19151360 | C2 | semidirect |
| 11. C22×C4⋊Dic89 | C4 | semidirect |
| 16. #19151360 | C22 | semidirect |
| 38. C2×C4⋊Dic89 | C2×C4 | semidirect |
| 163. C2×C89 | #1823 | semidirect |
| 174. C89 | C2×#1823 | semidirect |
| 331. C2 | #26020336 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
