Presentation

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

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

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