Presentation

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

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

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