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

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

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