3461 conjugacy classes of subgroups; only the 62 normal subgroups are shown.

normal subgroups only

This group has 3461 conjugacy classes of subgroups — too many to draw. Only its 62 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) = 96

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

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

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

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