Order 20224.
734 conjugacy classes of subgroups.
The subgroup lattice has 346 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23764174 | C2 | semidirect |
| 4. #23764172 | C2 | semidirect |
| 136. C2×Dic79 | #108 | semidirect |
| 180. C79 | #21969 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
