Order 20224.
538 conjugacy classes of subgroups.
The subgroup lattice has 266 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C2×#19098383 | C2 | semidirect |
| 4. #23761481 | C2 | semidirect |
| 116. C22×C79 | #364 | semidirect |
| 138. C79 | #12788 | semidirect |
| 249. C22 | #19098383 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
