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

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

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