228 conjugacy classes of subgroups; only the 128 normal subgroups are shown.
This group has 228 conjugacy classes of subgroups — too many to draw. Only its 128 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 26 points:
(1,2,3,4,5)(6,11,13,12,7,9,8,14,10)(19,20,21,22)(24,26);(7,9)(8,12)(10,11)(13,14)(15,16,17,18)(23,24)(25,26)420 conjugacy classes. The character table is too large to display.
