Presentation

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

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

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