I missed the 373 one!

And yes, I would discount the latter.

Unless I'm reading my prime number chart incorrectly, or it is indeed incorrect, I do have two solutions which contain the digit '1', like in 113.

Also please give me some thoughts on your listing.

Do, lines 110-160 provide the data for building the numbers formed by lines 221-237?

And why have you imposed a limit of 4 numbers since other digits occur in the three digit primes? 

And what part is the 'prime' test?
