Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 4 generators on 18 points:

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

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

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