Presentation

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

A minimal faithful permutation representation — 6 generators on 18 points:

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

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

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