Presentation

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

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

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

GAP

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

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