Order 20224.
1054 conjugacy classes of subgroups.
The subgroup lattice has 246 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23763150 | C2 | semidirect |
| 10. M16×Dic79 | C4 | semidirect |
| 34. #14579071 | C2×C4 | semidirect |
| 35. C8×Dic79 | C2×C4 | semidirect |
| 129. C79 | #20365 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
