Order 20224.
906 conjugacy classes of subgroups.
The subgroup lattice has 290 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23764162 | C2 | semidirect |
| 4. #23764160 | C2 | semidirect |
| 13. C2×Dic79⋊C8 | C4 | semidirect |
| 115. C2×Dic79 | #106 | semidirect |
| 152. C79 | #21959 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
