Presentation

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

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

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