Not at all. Do you think I would stuff my primitive cerebrum with the mere memorization of identities? But the looking up of them when necessary has been a great help.

Has knowing those factorisations come in handy?

Yes, I am ancient. You know that old quote:

The first hundred years is the hard part, after that it is all clear sailing.

So, I am guessing this book might be a bit difficult for me to find...

Wait, more than a century ago?!

The point is I had tables of them like a table of integrals or sums.

How does that relate to this? The wiki article is saying it is a factorisation of the form 24n+2 + 1.

More than a century ago, I came across a book with a big chart of Aurifeuillian Factorizations. I was amazed.

Yes but you never told me how you used cyclotomic polynomials to do that...

Hi;

Of course not:



To start, did you read post #2?

So you were able to pull that a^6 + 8b^6 factorisation off the top of your head?

Hi;

I threw it away in favor of a better program!

2012-10-21 07:45:40

Do you still have that computer program you used to compute factorisations?

2012-10-21 07:44:55

Oh, I see...

Hi;

That was a little bit of mathematical humor.
