A calculation of the linearization coefficients of the (generalized) Laguerre polynomials L")(x) is proposed by means of analytic and combinatorial methods. This paper extends to the case of an arbitrary a a combinatoric and analytic result due to Askey, Ismail, and Koornwinder and Even and Gillis.
