Presentation

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

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

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