I tend to agree. I don't know is it just a habit or something else, like a conservative profile of myself and many others, but that doesn't really matter.

The new site isn't that much better. Should be substantially better than this one for a smooth transition.

Please, focus only on what has been said and not on how it has been said.

Now, there is a possibility that all is wrong from my side. Of course I think how right I am, but everybody thinks that anyway. Including this Temple guy with his "don't code yet"! I wonder what people here think about that. ...(read more)

> Knowledge is information error-corrected (adapted) to a purpose (problem).

No. Knowledge is just information. If you have some information how to solve a particular problem, it's still "just information".

> There are no hard and fast rules about *how* error-corrected or to *what*

Those rules ...(read more)

I don't like it, at all.

As you see, my argumentation for that is just like yours. Nonexistent.

There are 143 primes between 100 and 999. We can, therefore, make 2,924,207 3x3 different squares with 3 horizontal primes. 50,621 of them have all three vertical numbers prime. About 1.7%.

There are 1061 primes between 1000 and 9999. We can, therefore, make 1,267,247,769,841 4x4 different squares ...(read more)

Say, that we have N-1 lines, with N-1 primes. Each N digits. What we now need is an N digit prime number to put it below.

Its most significant digit may be 1, 3, 7 or 9. Otherwise, the leftmost vertical number wouldn't be prime. If the sum of all N-1 other rightmost digits is X, then:

If X mod 3 ...(read more)

Interesting line of inferring... I am quite aware how dense primes are, but that might not be enough.

I have counted all these 4x4 (decimal) **crossprimes**. There are 913,425,530 of them if leading zeros are allowed. But only 406,721,511 without leading zeros.

if leading zeros ARE allowed, then t...(read more)

Well, I said something in line with "people may need some stuff to live and declaring that we should "put people before that stuff" is a silly way to present the situation". Maybe not as silly as it's a demagoguery.

But then I changed my mind and decided to not participate in a discussion at all. B...(read more)
