Presentation

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

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

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

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

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