The smallest prime p whose pth power pp contains a pandigital substring: 163163 = 38599...(5941863207)...95547. Note that π(163) is a semiprime with larger prime factor 19 which is the smallest prime q whose qth power qq is pandigital, and that the concatenations 16319 and 19163 are also primes. [Beedassy]
