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

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

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