Presentation

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

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

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