200 conjugacy classes of subgroups; only the 27 normal subgroups are shown.
This group has 200 conjugacy classes of subgroups — too many to draw. Only its 27 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((1,7,4)(2,5,6)(3,8,9)(11,15,16,14,19,12,13,20,17,18), (2,8,6,7)(3,5,4,9)(10,11,14,19,13,16,20,15,18,17,12));
