Presentation

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

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

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