5150 conjugacy classes of subgroups; only the 3614 normal subgroups are shown.
This group has 5150 conjugacy classes of subgroups — too many to draw. Only its 3614 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

A minimal faithful permutation representation — 5 generators on 31 points:
(1,2)(21,22,23,24,25,26,27,28,29,30,31);(3,4);(5,6,7,8)(13,14)(15,18)(16,17)(19,20);(9,10,11,12)(14,17)(18,20);(13,15,16,19)(14,18,17,20)1760 conjugacy classes. The character table is too large to display.
