Presentation

minimal degreeμ(G) = 17
transitive degreeμt(G) = 108

A minimal faithful permutation representation — 3 generators on 17 points:

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