3046 conjugacy classes of subgroups; only the 72 normal subgroups are shown.

normal subgroups only

This group has 3046 conjugacy classes of subgroups — too many to draw. Only its 72 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 — 3 generators on 20 points:

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