Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 128

GAP

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

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