We show that for all polynomials *Q*(*x*) with integer coefficients, that satisfy the extra condition *|Q*(0) *· Q*(1) *|* ≠ 1, there are infinitely many positive integers *n *such that *n *is a *τ*-number relative to the polynomial *Q*(*x*). We also find some examples of polynomials *Q*(*x*) for which 1 is the only *τ*-number relative to the polynomial *Q*(*x*) and some examples of polynomials *Q*(*x*) with |*Q*(0) *· Q*(1)*|*= 1, which have infinitely many positive integers *n *such that *n *is a *τ*-number relative to the polynomial *Q*(*x*). In addition, we prove one result about the generators of a *τ*-number.
