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

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

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