## Abstract

For random equiprobable Boolean functions we investigate the distribution of the number of subfunctions which have a given number of variables and are close to the set of affine Boolean functions. It is shown, for example, that for Boolean functions of n variables the mean number of subfunctions having s ⩾ 3 + log2n variables and the Hamming distance to the set of affine functions smaller than 2s−2 tends to 0 as n → ∞.
