Presentation

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

A minimal faithful permutation representation — 6 generators on 20 points:

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

GAP

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

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