• Triangle whose (i,j)-th entry is binomial(i,j)*7^(i-j)*9^j.at n=18A038275
• Triangle whose (i,j)-th entry is binomial(i,j)*9^(i-j)*7^j.at n=17A038297
• Triangle read by rows: (1/n)*T(n,h), where T(n,h) is the array in A101817.at n=31A101818
• 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=5A156322
