1866 conjugacy classes of subgroups; only the 155 normal subgroups are shown.

normal subgroups only

This group has 1866 conjugacy classes of subgroups — too many to draw. Only its 155 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 19
transitive degreeμt(G) = 144

A minimal faithful permutation representation — 3 generators on 19 points:

(1,2,4)(3,8,9)(5,7,6)(12,13,17,19,15,18,14,16);(2,8,6,3)(4,5,7,9)(10,11);(13,16)(14,17)(18,19)
