Order 20224.
578 conjugacy classes of subgroups.
The subgroup lattice has 388 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23761225 | C2 | semidirect |
| 4. #23761222 | C2 | semidirect |
| 29. #14579140 | C8 | semidirect |
| 60. C2×Dic158 | C2×C8 | semidirect |
| 72. C4⋊Dic79 | C2×C8 | semidirect |
| 199. C79 | #7589 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
