426 conjugacy classes of subgroups; only the 274 normal subgroups are shown.
This group has 426 conjugacy classes of subgroups — too many to draw. Only its 274 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 17 points:
(1,2)(11,12,13,14,15,16,17);(3,4,5,6);(7,8,9,10);(8,10)280 conjugacy classes. The character table is too large to display.
