Order 20224.
1310 conjugacy classes of subgroups.
The subgroup lattice has 380 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 21. #391×C79 | C4 | semidirect |
| 82. C2×Q8×C79 | C4⋊C4 | semidirect |
| 196. C79 | #14501 | semidirect |
| 204. #391 | Dic79 | semidirect |
| 255. C2×Q8 | C4⋊Dic79 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
