Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 20 points:

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

GAP

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

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