Order 33664.
568 conjugacy classes of subgroups.
The subgroup lattice has 256 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 10. C2×C4×Dic263 | C4 | semidirect |
| 13. C263⋊#95 | C4 | semidirect |
| 127. C263 | #1434 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
