Presentation

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

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

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

GAP

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

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