Pandigital Primes
A \((1,k)\)-pandigital integer is any number which contains all the digits from \(1\) to \(k\) exactly once each. A \((0,k)\)-pandigital integer is any number which contains all the digits from \(0\) to \(k\) exactly once each. We are interested in counting how many \((1,k)\)-pandigital prime numbers exist.
Part A | How many \((1,7)\)-pandigital prime numbers are there? | |
---|---|---|
Part B | How many \((0,7)\)-pandigital prime numbers are there? |
