Order 18688.
626 conjugacy classes of subgroups.
The subgroup lattice has 358 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C2×#17988369 | C2 | semidirect |
| 2. #22607867 | C2 | direct (N × H) |
| 6. #17988369 | C22 | semidirect |
| 177. C2×C73 | #1320 | semidirect |
| 182. C73 | C2×#1320 | semidirect |
| 355. C2 | #22607867 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
