Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 18 points:

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

GAP

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

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