Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 128

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

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

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