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

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

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