minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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