Order 20224.
1350 conjugacy classes of subgroups.
The subgroup lattice has 246 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #23763551 | C2 | semidirect |
| 58. C4×Dic79 | M16 | semidirect |
| 112. C4×C79 | #423 | semidirect |

| 128. C79 | #20791 | semidirect |
| 237. C4 | #19098586 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
