Order 22784.
1734 conjugacy classes of subgroups.
The subgroup lattice has 454 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #26020330 | C2 | direct (N × H) |
| 4. C2×#19151366 | C2 | semidirect |
| 22. #19151366 | C22 | semidirect |
| 223. C2×C89 | #1821 | semidirect |
| 232. C89 | C2×#1821 | semidirect |
| 449. C2 | #26020330 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
