272 conjugacy classes of subgroups; only the 152 normal subgroups are shown.
This group has 272 conjugacy classes of subgroups — too many to draw. Only its 152 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

A minimal faithful permutation representation — 3 generators on 35 points:
(1,2)(23,24,25,26,27,28,29,30,31,32,33,34,35);(3,4)(5,6)(7,8,9,12,10,13,15,18,11,14,16,19,17,20,21,22);(4,6)1040 conjugacy classes. The character table is too large to display.
