Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 32 points:

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