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