Presentation

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

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

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