40954 conjugacy classes of subgroups; only the 85 normal subgroups are shown.

normal subgroups only

This group has 40954 conjugacy classes of subgroups — too many to draw. Only its 85 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 80

A minimal faithful permutation representation — 3 generators on 21 points:

(2,3)(4,5)(7,12,13)(8,10,11)(15,16,18)(19,20,21);(1,2,4,5,3)(7,10)(11,13)(15,18,19,21)(16,20);(6,10)(7,8)(9,13)(11,12)(14,18)(15,16)(17,21)(19,20)

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

gap> G := Group((2,3)(4,5)(7,12,13)(8,10,11)(15,16,18)(19,20,21), (1,2,4,5,3)(7,10)(11,13)(15,18,19,21)(16,20), (6,10)(7,8)(9,13)(11,12)(14,18)(15,16)(17,21)(19,20));
