Presentation

minimal degree	μ(G) = 64
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 64 points:

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