Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 32 points:

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