Order 20224.
780 conjugacy classes of subgroups.
The subgroup lattice has 370 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23764173 | C2 | semidirect |
| 5. C4×#14579096 | C2 | semidirect |
| 138. C2×C4×C79 | #108 | semidirect |
| 191. C79 | #21370 | semidirect |
| 323. C2×C4 | #14579096 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
