Presentation

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

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

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