136 conjugacy classes of subgroups; only the 60 normal subgroups are shown.
This group has 136 conjugacy classes of subgroups — too many to draw. Only its 60 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

A minimal faithful permutation representation — 2 generators on 23 points:
(1,2,3,4,5,6,7)(8,9,11,12,10)(14,15)(21,23);(9,10)(11,12)(13,14,15)(16,17,18,19)(20,21)(22,23)294 conjugacy classes. The character table is too large to display.
