440 conjugacy classes of subgroups; only the 392 normal subgroups are shown.
This group has 440 conjugacy classes of subgroups — too many to draw. Only its 392 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

A minimal faithful permutation representation — 4 generators on 31 points:
(1,2)(19,20,21,22,23,24,25,26,27,28,29,30,31);(3,4,5,6,7,8,9,10);(11,12,13,14)(15,18,17,16);(11,15,13,17)(12,16,14,18)1040 conjugacy classes. The character table is too large to display.
