Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 512

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

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

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

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