Presentation

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

GAP

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

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