Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 8 generators on 20 points:

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

GAP

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

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