cp's OEIS Frontend

This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

A058760 Integers whose set of prime factors (taken with multiplicity) uses each digit exactly once (i.e., is pandigital) in some base b > 1. Numbers are expressed in base 10.

Note that the appropriate base for each number is not given here.

Examples

			19 in base 3 is 201, which is pandigital, so it qualifies (having just itself as a prime factor). A more elaborate example is 5662 = 2 * 19 * 149, which in base 6 is 2 * 31 * 405, also pandigital.
