Presentation

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

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

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