Presentation

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

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

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