Presentation

minimal degreeμ(G) = 38
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 38 points:

(1,2);(3,4)(5,6);(7,8,10,15,11,16,22,32,12,14,23,29,24,30,37,38)(9,17,19,33,20,13,25,27,18,28,21,35,34,26,36,31);(7,9)(8,13,14,26)(10,21)(11,20)(12,18)(15,31,29,27)(16,28,30,17)(19,23)(22,36)(24,34)(25,37)(32,33,38,35);(4,6)(8,14)(9,18)(15,29)(16,30)(19,21)(20,34)(25,36)(32,38)

GAP

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), (7,8,10,15,11,16,22,32,12,14,23,29,24,30,37,38)(9,17,19,33,20,13,25,27,18,28,21,35,34,26,36,31), (7,9)(8,13,14,26)(10,21)(11,20)(12,18)(15,31,29,27)(16,28,30,17)(19,23)(22,36)(24,34)(25,37)(32,33,38,35), (4,6)(8,14)(9,18)(15,29)(16,30)(19,21)(20,34)(25,36)(32,38));
