Wow- Congrats to All! I wonder if this will generate a new button...

If so, I'm asking for one...

Some years ago, if I remember correctly, someone sold a poster with the decimal expansion of newly discovered primes (a magnifying glass was necessary to read the digits).
Does it still exist ?

I have one of those posters.
Unfortunately, Richard Crandall (owner of Perfectly Scientific Inc.) is no more among us mortals, and AFAIK no one took such heritage.
Consider however that even using a 1-point font, the offset needed for such a huge poster would be enormous.

I didn't know about Richard's death. I am sorry. I hope he rest in peace.

I talked with a printer that I know about making one as a banner. Let me contact them again. Allowing it to be a banner would give more room than off-set sheets.

Actually, there are too many primes being discovered in the current range.

There are:

4 between 10⁰ and 10¹
6 between 10¹ and 10²
4 between 10² and 10³
8 between 10³ and 10⁴
6 between 10⁴ and 10⁵
5 between 10⁵ and 10⁶
5 between 10⁶ and 10⁷
11 between 10⁷ and 10⁸ (and now probably 12)

Congratulations!!!

Sweet dreams are made of this
Who am I to disagree?
I travel the forum
And the seven threads

Yes- When we had found 9 in the current range, I was convinced that was the end for this range. I was more convinced when we got to 10; and 11. Now, I'm only convinced that I'm wrong.

I suppose we code try to code up a test case that sent it to several dummy addresses plus Aaron and myself.... Given our PHP prowess we'd probably mess that up too.

I'm missing something blindingly obvious.

Send initial mail to three real people and a mailing list. The mailing list can contain Lord High Everything Else.

Needless to say, the contents of the mailing list should be kept Top Sekrit but it can be processed by industrial strength software, not some cobbled together home wrotten PHP script.

Currently it's hiding the prime status and result entirely.

Until last night it was easy to find if you knew where to look.
