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

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

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