For each integer $d\ge 4$, we study the sequence of positive integers whichare represented by one at least of the cyclotomic binary forms $\Phi_n(X,Y)$,with $n$ a positive integer satisfying $\varphi(n)\ge d$. The case $d=2$ wasstudied in our previous work [FLW]. Our demonstration is based on a variant ofa statement of [SX] concerning the common values taken by two binary forms ofthe same degree and non-zero discriminants. All constants are effectivelycalculable.
