Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 20 points:

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

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

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