Presentation

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

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

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