Appears in sequences

• Let x(0)x(1)x(2)... x(q) denote the decimal expansion of n. Sequence lists the numbers n such that the suffix of decimal expansion x(2)... x(q) is the p-th divisor of n where p is the prefix of decimal expansion x(0)x(1).at n=33A234315
• Least k formed by the concatenation of two numbers n and d such that d is the n-th divisor of k, or 0 if no such k exists.at n=28A257491
• Numbers m such that the concatenation of k and the k-th divisor of m is equal to m for some k.at n=26A258738
• Numbers n that have a record maximum in their unitary aliquot sequence.at n=12A290145
