Presentation

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

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

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