Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 48

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

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