“…More than 40 years ago, P. Turán [7] asked if every polynomial with integer coefficients lies near an irreducible polynomial with the same degree or smaller, where distance is measured by using the length. More precisely, he asked if there exists an absolute constant C such that for every polynomial f ∈ Z[x] there exists an irreducible polynomial g ∈ Z[x] with deg(g) ≤ deg(f ) and L(f − g) ≤ C. Note that if such a constant C exists, then certainly C ≥ 2, as this value is required for f (x) = x n when n is odd and n ≥ 3, or for f (x) = x n−2 (x 2 + x − 1) when n is even and n ≥ 4 .…”
