Presentation

minimal degreeμ(G) = 64
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 3 generators on 64 points:

(1,2)(3,12,14,22)(4,17)(5,19)(6,9)(7,11)(8,13,23,16)(10,21)(15,30,29,27)(18,25)(20,26)(24,31,32,28)(33,34,35,39,36,40,43,49,37,41,44,50,46,52,55,59,38,42,45,51,47,53,56,60,48,54,57,61,58,62,63,64);(1,3,5,15,6,16,20,31,7,14,21,29,4,13,18,28)(2,8,10,24,9,22,25,30,11,23,19,32,17,12,26,27);(1,4,7,6)(2,9,11,17)(3,13,14,16)(5,18,21,20)(8,22,23,12)(10,25,19,26)(15,28,29,31)(24,30,32,27)
