Hi all,
Problem 630 has been driving me up the wall for a few days now - I'm sure I'm missing something really stupid but I can't figure it out yet.
Could someone perhaps confirm that I've at least got the correct number of (unique) lines: I get 3***890...
Cheers,
Claude

Sorry, your last 3 digits of the number of lines are all wrong.

Thanks Animus, I'll have another look at that bit then

Well, this one is still haunting me. I now get a total of 3***626 unique lines.
Could someone check whether this seems correct (and if not possibly let me know the last couple of digits so I'll know when I'm approaching the answer - or would that already be a form of cheating?)
Cheers,
Claude
