Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 160

A minimal faithful permutation representation — 4 generators on 20 points:

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

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

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