Hi Thea

It rings no bells at all with me - do you have any more clues you can offer?

Hi, Thea,

Like tatters, I also don’t remember the puzzle to which you refer.

Hi there -- at the risk of being a pest the problem was to find the integers P,Q.and R such that P+Q, P+R, Q+R, P-Q, P-R and Q-R were all perfect squares . Tatters suggested an answer, wintonian gave a method with generating formula based on Pythagorean Triples. Hope you can point to where it may lie in the forum archive. Probably early April.

Kind Regards Thea(o)

Hi, I remember this now, but it was actually in mid-February. The thread is called "Algebra !!!!!", and if you put the word "Algebra" into the search box at the top of the page, it should take you to the thread.

Hello wintonian Thank you very much for locating that puzzle -- Its amazing how things get buried. I was introduced to Pythags Triples in 1954 and still enjoy generating them and analysing them. Once again Thanks and good to meet you. Hope you have a good week in these peculiar times Thea(o)

Hi, glad to be of help. It took me a bit of time to find the puzzle as I'd used the term "Pythagorean triplets" in the original thread rather than "Pythagorean triples", which I understand is the more usual expression.

On some discussion forums (or should that be "fora"?), it's possible to get a list of all your posts, but this doesn't seem to be the case for the Crossword Help Forum. So I ended up using Google to search for the website's URL and my name.

Hi Wi ntonian That was a clever way to search ( I dont understand what an URL is!!!!
Some years back i investigated lame triples where one leg is a bit longer than the other . A good example is 20,21,29. As the numbers get bigger c/(a+b)/2 give an increasingly close approximation to Root2 ( of course c^2=a^2+ b^2). No need to reply Kind regards Thea(o)
