Glossary: Prime Pages: Top 5000: 
Have you every played the game where you take a word like "prime" and see how many other words you can find in it?
For example, you might find: prime, prim, ripe, imp, pie, rip, ... Why not play the same game with integers and
look for primes? For example, in 1379
we find the following thirtyone primes:
3, 7, 13, 17, 19, 31, 37, 71, 73, 79, 97, 137,(Note that we may only use as many of each digit as are present in the original number.) Mike Keith defined a primeval number to be a positive integer which contains more primes (in the way discussed above) than any smaller positive integer. Below are all of the primeval numbers less than 100,000 (from Keith's web page).
