minimal degreeμ(G) = 32
transitive degreeμt(G) = 64

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

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