Presentation

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

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

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