Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 512

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

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

GAP

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

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