Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 99

A minimal faithful permutation representation — 2 generators on 20 points:

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

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

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