712 conjugacy classes of subgroups; only the 309 normal subgroups are shown.
This group has 712 conjugacy classes of subgroups — too many to draw. Only its 309 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23781529 | C2 | direct (N × H) |
| 12. C2×C4×Dic163 | C4 | semidirect |
| 31. C4×Dic163 | C2×C4 | semidirect |

By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
