Presentation

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

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

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