Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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