70501 conjugacy classes of subgroups; only the 2229 normal subgroups are shown.

normal subgroups only

This group has 70501 conjugacy classes of subgroups — too many to draw. Only its 2229 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) = 128

A minimal faithful permutation representation — 5 generators on 20 points:

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