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=31A234315
• Indices of records in A371921: numbers k such that A371921(k) > A371921(m) for all m < k.at n=19A371922
