Order 18176.
1978 conjugacy classes of subgroups.
The subgroup lattice has 260 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #22597425 | C2 | direct (N × H) |
| 2. C2×#17986130 | C2 | semidirect |
| 6. #17986130 | C22 | semidirect |
| 126. C2×C71 | #2983 | semidirect |
| 135. C71 | C2×#2983 | semidirect |
| 255. C2 | #22597425 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
