Presentation

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

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

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