  We obtain rge Erd\" os-R\' enyi type law of large numbers for
"nonconventional" sums of the form $S_n=\sum^n_{m=1}F(X_m,X_{2m},...,X_{\ell
m})$ where $X_1,X_2,...$ is a sequence of i.i.d. random variables and $F$ is a
bounded Borel function. The proof relies on nonconventional large deviations
obtained in [8].
