Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 320

GAP

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

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