Presentation

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

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

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

GAP

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

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