%N Number of inequivalent binary linear codes of length n minus 2^n.
%C The numbers of inequivalent binary linear codes of length n (A076766) start like the powers of two (A000079). This sequence is their difference. These are the row sums of the triangle A250002.
%F a(n) = A076766(n) - A000079(n).
%e There are 342 inequivalent binary linear codes of length 8, and 2^8 = 256, hence a(8) = 342 - 256 = 86.
%Y Cf. A076766, A000079, A250002.
