Order 20224.
1294 conjugacy classes of subgroups.
The subgroup lattice has 330 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23764355 | C2 | direct (N × H) |
| 9. C2×#14579153 | C4 | semidirect |
| 31. #14579153 | C2×C4 | semidirect |
| 159. C2×C79 | #1989 | semidirect |
| 171. C79 | C2×#1989 | semidirect |
| 323. C2 | #23764355 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
