Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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