Order 20224.
994 conjugacy classes of subgroups.
The subgroup lattice has 340 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |

| 7. #19098423 | C4 | semidirect |
| 10. C4×C22⋊Dic79 | C4 | semidirect |
| 12. C2×#117×C79 | C4 | semidirect |
| 13. #381×C79 | C4 | semidirect |
