Presentation

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

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

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