Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

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

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