Presentation

minimal degreeμ(G) = 19
transitive degreeμt(G) = 112

A minimal faithful permutation representation — 4 generators on 19 points:

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

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

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