Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 40 points:

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