Presentation

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

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

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