Presentation

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

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

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