Presentation

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

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

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