RE: Fun with Numbers: The Pan-Prime-Digit Cube Hypothesis
I did it with a list of all 6-digit integer candidates (7 did not work, out of Memory on my virtual Prime) and then started a brute force attack in a loop, after cubing I first ruled out the first digit if it was 1, only then I checked all digits to be 2,3,5 or 7. Took about an hour to find the first solution, as it makes intense use of strings. So I now start thinking about another way to rule out digits from the beginning.
