Presentation

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

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

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