So I guess everyone learned the answer to the question I wrote before,
How many 1BY8GQbnueY starts are there in our 67 bit range? The correct answer is 4.

where does 4 come from if there were 2?

it will take another couple of days and it turns out that it is no longer 2 or 4, or even 16, but 21, or maybe more))))

Yes, you are very funny, really.

Now go put on your glasses.

Then dream. Then wake up in the morning and see if they are still there.
I disagree with you. Firstly, puzzle #67 has a range width of 66 bits.
The second is that 1BY8GQbnueY has a length of 56 bits and accordingly in the entire range of 66 bits there are approximately 1024 such combinations.
1BY8GQbnueY How did you know it was 56 bit?
