934 conjugacy classes of subgroups; only the 442 normal subgroups are shown.
This group has 934 conjugacy classes of subgroups — too many to draw. Only its 442 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 40 points:
(1,2);(3,4);(5,6)(7,8)(9,10,11,15,12,16,19,25,13,17,20,26,22,28,31,35,14,18,21,27,23,29,32,36,24,30,33,37,34,38,39,40);(6,8)320 conjugacy classes. The character table is too large to display.
