212 conjugacy classes of subgroups; only the 90 normal subgroups are shown.

normal subgroups only

This group has 212 conjugacy classes of subgroups — too many to draw. Only its 90 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)(11,14,15,22,17,23,16,13)(12,18,19,25,20,26,24,21);(11,13)(12,18)(14,15)(16,23)(17,22)(19,25)(20,26)(21,24);(9,10)(11,12)(13,21)(14,18)(15,19)(16,24)(17,20)(22,25)(23,26)
