  Puzzle 138.  Deletable primes
A deletable prime has been defined ([Caldwell87]) to be a prime that you can delete the digits one at a time in some order and get a prime at each step.
For example, the prime 523 can be constructed from the prime 2 or from the prime 3 or from the prime 5.
In order to support that this is a deletable prime he sent also the other 499 primes involved in the del500oneodd.txt file 128 Kb large.
