388 conjugacy classes of subgroups; only the 130 normal subgroups are shown.
This group has 388 conjugacy classes of subgroups — too many to draw. Only its 130 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. #64919 | C2 | semidirect |

| 137. C5 | #1742 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
