Let t(j,k) = log(j)*log(k) and let d(j,k) be the absolute difference of t(j,k) and the nearest integer, i.e., d(j,k) = |t(j,k) - round(t(j,k))|. This sequence lists the numbers j at which a record low value of d(j,k) (i.e., lower than for any other pair (j',k') satisfying 2 <= k' <= j' <= j) occurs. Corresponding values of k are in A341653.
