The smallest unrestricted pandigital primes must therefore have 11 digits (no two of which can be 0). The first few unrestricted pandigital primes are therefore 10123457689, 10123465789, 10123465897, 10123485679, ... (OEIS A050288 ). WebYou are correct if these four numbers are any numbers $0001$ to $9999$. There are $9999$ possible numbers. However, it is possible that the first three digits are any value $0$ to $9$ and the last digit is any value $1$ to $9$. In this case there are $10\times10\times10\times9 = 9000$ ways to fill out these four digits. incompatibility\u0027s 7n
