256 conjugacy classes of subgroups; only the 74 normal subgroups are shown.
This group has 256 conjugacy classes of subgroups — too many to draw. Only its 74 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 24 points:
(1,2,3,4,5)(6,7,8)(10,14)(16,21);(7,8)(9,10,11,15,12,16,18,22,13,14,17,20,19,21,23,24)270 conjugacy classes. The character table is too large to display.
