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

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

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