Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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