408 conjugacy classes of subgroups; only the 80 normal subgroups are shown.
This group has 408 conjugacy classes of subgroups — too many to draw. Only its 80 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 29 points:
(1,2,3,4,5)(14,28,23,21,24,29,18,19,25,15,16,27)(17,20,22,26);(6,8,9,13)(7,10,11,12);(6,7,9,11)(8,12,13,10)(16,22)(17,24)(19,26)(20,28)(23,25)(27,29)230 conjugacy classes — view the full character table.
