|It's possible to spell words using only the letters found in hexadecimal numbers (A, B, C, D, E, F).
For example, "DEFACE," "BEADED" etc. In this Puzzlet, you can use words of any length, and repeat as many letters as you wish, as long as the word can be found in a published dictionary.
Example: DAB, which is equal to 3499 in denary, is a prime number.
Using the rules defined above, how many words can you find which are also prime numbers when evaluated as true hexadecimal numbers?
