We prove that, in order to derive the HOMFLYPT skein module of the lens spaces L(p, 1) from the HOMFLYPT skein module of the solid torus, S(ST), it suffices to solve an infinite system of equations obtained by imposing on the Lambropoulou invariant X for knots and links in the solid torus, braid band moves that are performed only on the first moving strand of elements in a set Lambda(aug), augmenting the basis. of S(ST).
