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

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

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