456 conjugacy classes of subgroups; only the 170 normal subgroups are shown.
This group has 456 conjugacy classes of subgroups — too many to draw. Only its 170 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

A minimal faithful permutation representation — 3 generators on 23 points:
(1,2,3,4,5)(6,7,8,9)(11,15)(12,16)(21,22,23);(10,12,13,16)(11,14,15,17)(18,19,20);(10,11)(12,14)(13,15)(16,17)(19,20)(22,23)300 conjugacy classes. The character table is too large to display.
