• Triangle whose (i,j)-th entry is binomial(i,j)*12^(i-j)*8^j.at n=24A038334
• a(n) = Product_{k=1..n} d(k); d(k) = A000005(k) is the number of positive divisors of k.at n=16A066843
• a(n) = [n/1][n/2][n/3] ...[n/n] / n^(tau(n)/2).at n=32A076891

• Integer values of n!!/sum(i=0..n,n), with n>=1.at n=6A130332
• Integers n such that if you insert between each of their digits either "*" (times), "^" (exponentiation), or "nothing" (so that two or more digits are merged to form an integer), then you can recover n in a nontrivial way (however, two "^" mustn't be adjacent - you must avoid decompositions containing a^b^c).at n=29A156322
