3342 conjugacy classes of subgroups; only the 715 normal subgroups are shown.
This group has 3342 conjugacy classes of subgroups — too many to draw. Only its 715 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.
