9385 conjugacy classes of subgroups; only the 589 normal subgroups are shown.

normal subgroups only

This group has 9385 conjugacy classes of subgroups — too many to draw. Only its 589 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 — 5 generators on 20 points:

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

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

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