Order 22784.
4158 conjugacy classes of subgroups.
The subgroup lattice has 264 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. C2×#19151530 | C2 | direct (N × H) |
| 16. #19151530 | C22 | direct (N × H) |
| 109. C22×C89 | #398 | semidirect |
| 126. C2×C89 | C2×#398 | semidirect |
| 138. C89 | C22×#398 | semidirect |
| 241. C22 | #19151530 | direct (N × H) |
| 257. C2 | C2×#19151530 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
