Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 40 points:

(1,2,4,6,5,8,3,7)(9,10)(11,19)(12,23,25,17)(13,26,28,16)(14,18)(15,20,31,37)(21,38,27,34)(22,35)(24,33)(29,32)(30,36)(39,40);(2,6)(3,4)(7,8)(9,11,14,22)(10,15,18,31)(12,20,25,37)(13,27,28,21)(16,30,26,40)(17,19,23,35)(24,39,29,36)(32,38,33,34);(10,16,18,26)(13,28)(15,30,31,40)(17,33,23,32)(19,34,35,38)(21,27)(24,29)(36,39)
