Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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