Presentation

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

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

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

GAP

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

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