Presentation

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

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

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