456 conjugacy classes of subgroups; only the 246 normal subgroups are shown.
This group has 456 conjugacy classes of subgroups — too many to draw. Only its 246 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)(7,8,10,11,9)(12,13,14,15)(17,21)(20,23);(4,5,6)(16,18,19,22)(17,20,21,23);(8,9)(10,11)(16,17)(18,20)(19,21)(22,23)468 conjugacy classes. The character table is too large to display.
