Presentation

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

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

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