3701 conjugacy classes of subgroups; only the 87 normal subgroups are shown.
This group has 3701 conjugacy classes of subgroups — too many to draw. Only its 87 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((4,7,5)(8,9,10)(12,16,17,14,15,19)(13,18), (1,2)(4,8)(5,10)(11,15,19,13,12,14,18,17,16), (3,9,6,7)(4,5,8,10));
