348 conjugacy classes of subgroups; only the 110 normal subgroups are shown.
This group has 348 conjugacy classes of subgroups — too many to draw. Only its 110 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 28 points:
(1,2,3,4,5)(6,7)(13,14,17,20)(15,22,24,28)(16,25,23,19)(18,26,27,21);(9,10,11,12);(7,8)(10,12)(14,18)(15,21)(16,23)(19,28)(20,27)(22,25)(24,26)345 conjugacy classes. The character table is too large to display.
