For K a field of characteristic zero, let M(K) denote the set of Drinfel’d associators defined over K [Dr]. The variety M is of great interest because of its connection to the deformations of universal enveloping algebras, fundamental group of the Teichmuller tower, and to Gal(Q/Q). There is a natural map M → A and for λ ∈ K, and Mλ is a torsor under GRT1 (= M0). If K << X,Y >> denotes the formal associative power series in X and Y over K then GRT1(K) is defined to be the set of elements φ ∈ K << X,Y >> that satisfy
