Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 3 generators on 32 points:

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