“…which depend on integration contour (knot) K, the coupling constant g, the size N of the sl N gauge algebra and its representation R. Dependence on g and N is actually through the non-perturbative variables q = exp 2πi g+N and A = q N , of which H K is -mysteriously -just a polynomial. For a recent progress in perturbative approach see [51,52]. Dependence on K and R is more tricky, and the better (less redundant) variables are the coefficients F K Q of the differential (cyclotomic) expansion , which we write down restricted in two ways -to symmetric representations and to defect [23] zero -according to the limited consideration in this paper.…”

For a peculiar family of double braid knots there is a remarkable factorization formula for the coefficients of the differential (cyclotomic) expansion (DE), which nowadays is widely used to construct the exclusive Racah matrices S and S in arbitrary representations. The origins of the factorization remain obscure and the special role of double braids remains a mystery. In an attempt to broaden the perspective, we extend the family of double braids to antiparallel triple pretzels, which are obtained by the defect-preserving deformation from the trefoil and all have defect zero. It turns out that factorization of DE coefficients is violated quite strongly, still remains described by an elegant formula, at least for all symmetric representations.
