Presentation

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

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

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