2642 conjugacy classes of subgroups; only the 266 normal subgroups are shown.
This group has 2642 conjugacy classes of subgroups — too many to draw. Only its 266 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((7,8,10)(9,14,15)(11,13,12)(18,19), (4,5,6)(8,14,12,9)(10,11,13,15)(16,17), (1,2,3));
