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