Presentation

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

A minimal faithful permutation representation — 4 generators on 38 points:

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