Presentation

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

A minimal faithful permutation representation — 2 generators on 40 points:

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