468 conjugacy classes of subgroups; only the 154 normal subgroups are shown.
This group has 468 conjugacy classes of subgroups — too many to draw. Only its 154 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)(9,10,11)(13,15)(18,22)(20,23);(6,7,8)(16,18)(17,20)(19,22)(21,23);(7,8)(10,11)(12,13)(14,15)(16,17,19,21)(18,20,22,23)270 conjugacy classes. The character table is too large to display.
