Presentation

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

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

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