minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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