Presentation

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

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

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