Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 7 generators on 20 points:

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

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

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