184 conjugacy classes of subgroups; only the 106 normal subgroups are shown.
This group has 184 conjugacy classes of subgroups — too many to draw. Only its 106 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. #64888 | C2 | direct (N × H) |
| 33. C2×Dic5 | C16 | semidirect |
| 55. Dic5 | C2×C16 | semidirect |
| 68. C2×C5 | C4⋊C16 | semidirect |
| 85. C5 | C2×C4⋊C16 | semidirect |
| 95. C2 | #64888 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
