Presentation

minimal degreeμ(G) = 17
transitive degreeμt(G) = 224

A minimal faithful permutation representation — 5 generators on 17 points:

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

GAP

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

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