Presentation

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

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

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