Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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