Order 20224.
1026 conjugacy classes of subgroups.
The subgroup lattice has 298 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23763268 | C2 | semidirect |
| 4. #23763266 | C2 | semidirect |
| 11. #19098613 | C4 | semidirect |
| 40. Dic79⋊C8 | C2×C4 | semidirect |
| 44. C8×Dic79 | C2×C4 | semidirect |
| 119. C2×Dic79 | #97 | semidirect |
| 156. C79 | #20536 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
