%N The number of eigenvectors with eigenvalue 1 summed over all linear operators on the vector space GF(2)^n.

%C Generally, for any prime power q, the total number of eigenvectors corresponding to any element lambda in the field GF(q) summed over all operators on GF(q)^n is equal to (q^n-1)*q^(n^2-n).

%F a(n) = (2^n-1)*2^(n^2-n).

%t Map[Total,Table[Table[(q^(n - k) - 1) Product[(q^n - q^i)^2/(q^k - q^i), {i, 0,k - 1}] /. q -> 2, {k, 0, n}], {n, 0, 11}]]

%Y Cf. A286331.
