686 conjugacy classes of subgroups; only the 39 normal subgroups are shown.
This group has 686 conjugacy classes of subgroups — too many to draw. Only its 39 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
gap> G := Group((1,2,3,4,9,5,7,8)(11,15,14,12,13,16), (2,4,9)(3,6,7)(10,11,14,15,13,16,12)(17,18));
