Problem 669

I've come up with what I thought was a unique solution for the n=34 case, but I don't have knight 30 sitting in the 3rd chair from the king's left. My solution starts 4-30-25-9-12-... (not posting it all as I think it may give away the pattern needed to solve the puzzle). Any pointers people can give me? I'd be surprised if an error had got through this far, although there's still a typo in the text: "the king always prefers an arrangement where the knight to the his left". Thanks in advance.

Ok, I'm stupid. (I'd not realised I hadn't used all the numbers.) I now have a solution which fits the rubric.

Ask me again about Problem 669 in the year 2040 again. I have an alogorithm, but it will run for 20 years until it prints the solution. I hope I do not run into any date problems during the wait.

Oh, I am lucky, i made an error in judging the situation: I will have the solution already in 1.92 years :-)
