Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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