286 conjugacy classes of subgroups; only the 32 normal subgroups are shown.

normal subgroups only

This group has 286 conjugacy classes of subgroups — too many to draw. Only its 32 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 60

A minimal faithful permutation representation — 2 generators on 20 points:

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