• Consider the array T(n, m) where the n-th row is the sequence of integer coefficients of A(x), where 1<=a(n)<=n, such that A(x)^(1/n) consists entirely of integer coefficients and where m is the (m+1)-th coefficient. This is the row sum of A to the first coefficient of one.at n=43A112285
• Ratio of each term of the primorial function to the corresponding term of the factorial function (rounded to nearest integer).at n=13A123389
• a(n) = floor( Product_{i=1..n} prime(i)/i ).at n=14A135568
