204 conjugacy classes of subgroups; only the 134 normal subgroups are shown.

normal subgroups only

This group has 204 conjugacy classes of subgroups — too many to draw. Only its 134 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)(11,13,15,23,16,21,14,22)(12,17,18,20,19,25,24,26);(13,21)(17,25)(20,26)(22,23);(9,10)(11,12,14,18,16,19,15,24)(13,20,22,25,21,26,23,17)
