Presentation

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

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

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