196 conjugacy classes of subgroups; only the 48 normal subgroups are shown.
This group has 196 conjugacy classes of subgroups — too many to draw. Only its 48 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 29 points:
(1,2,3,4,5)(6,7,8,10,9,11,12,13)(14,24,26)(15,20,29,19,25,28)(16,23,18)(21,22);(14,15,18,19)(16,22,24,21)(17,25,27,20)(23,29,26,28)260 conjugacy classes. The character table is too large to display.
