200 conjugacy classes of subgroups; only the 106 normal subgroups are shown.
This group has 200 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. #64884 | C2 | direct (N × H) |
| 24. C2×#168 | C8 | semidirect |
| 43. #168 | C2×C8 | semidirect |
| 77. C2×C5 | #335 | semidirect |
| 96. C5 | C2×#335 | semidirect |
| 109. C2 | #64884 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
