4068 conjugacy classes of subgroups; only the 115 normal subgroups are shown.

normal subgroups only

This group has 4068 conjugacy classes of subgroups — too many to draw. Only its 115 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) = 64

A minimal faithful permutation representation — 4 generators on 20 points:

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