Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 128

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

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

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

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