minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

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

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