Order 20224.
1292 conjugacy classes of subgroups.
The subgroup lattice has 322 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×#19098612 | C2 | semidirect |
| 3. #23763450 | C2 | semidirect |
| 4. C2×C79⋊#338 | C2 | semidirect |
| 8. C2×#14579097 | C22 | semidirect |
| 13. C79⋊#338 | C22 | semidirect |
| 166. C79 | #20673 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
