Presentation

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

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

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