Presentation

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

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

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

GAP

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

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