Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 5 generators on 32 points:

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