    The main result is that the identities of the free n-generator metabelian (nonassociative) algebra over an associative, commutative ring are infinitely based. More precisely, the identities \[ t_{n,k}=\sum_{\sigma \in S_{k+1}}(-1)^{\sigma}L(x_{\sigma_ 1})...L(x_{\sigma_ k})L(x_ k),...^{n-times},L(x_ k)L(x_{\sigma (k+1)}) \] are not consequences of polylinear identities of length \(\leq n+k\).
