912 conjugacy classes of subgroups; only the 50 normal subgroups are shown.

normal subgroups only

This group has 912 conjugacy classes of subgroups — too many to draw. Only its 50 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 15
transitive degreeμt(G) = 54

A minimal faithful permutation representation — 3 generators on 15 points:

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