216 conjugacy classes of subgroups; only the 89 normal subgroups are shown.
This group has 216 conjugacy classes of subgroups — too many to draw. Only its 89 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 |

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