Presentation

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

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

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

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

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