Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 160

A minimal faithful permutation representation — 4 generators on 20 points:

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

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

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