308 conjugacy classes of subgroups; only the 118 normal subgroups are shown.

normal subgroups only

This group has 308 conjugacy classes of subgroups — too many to draw. Only its 118 normal subgroups are shown.

Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 336

A minimal faithful permutation representation — 3 generators on 26 points:

(1,2,3,4,5,6,7)(8,9,10)(12,17,18,19)(13,20)(16,23,24,25)(21,26);(11,13)(12,16)(14,21)(15,20)(17,25)(18,24)(19,23)(22,26);(9,10)(11,12)(13,16)(14,17)(15,18)(19,22)(20,24)(21,25)(23,26)
