725 conjugacy classes of subgroups; only the 206 normal subgroups are shown.
This group has 725 conjugacy classes of subgroups — too many to draw. Only its 206 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 27 points:
(1,2,3,4,5,6,7,8,9);(10,11,13,12,14,16,15,17,18)(19,20,23)(21,25,22)(24,27,26);(19,21,25,22,24,27,26,20,23)459 conjugacy classes. The character table is too large to display.
