Presentation

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

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

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

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

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