Presentation

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

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

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