Letting T_n (resp. U_n) be the n-th Chebyshev polynomials of the first (resp. second) kind, we prove that the sequences (X^kT_n-k)_k and (X^kU_n-k)_k for n - 2⎣n/2⎦ ≤ k ≤ n - ⎣n/2⎦ are two basis of the ℚ-vectorial space _n[X] formed by the polynomials of ℚ[X] having the same parity as n and of degree ≤ n. Also T_n and U_n admit remarkableness integer coordinates on each of the two basis.
Keywords: Chebyshev polynomials, integer coordinates
