Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 20 points:

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

GAP

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

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