Re: VanitySearch (Yet another address prefix finder)

This is not exactly the answer to my question - "Is there a number that creates a range that makes up 100% of the pool in which the prefix is located?"

However, thanks for the calculation and explanation.
What the case looks like in case of difficulties 10054102514374868992
What percentage does this number specify? (I can't find an effective calculation method myself)

I'm not sure to fully understand the question.
If I understand well, there is no way to define a group with a specific size where you are 100% sure that a given prefix is located because addresses are randomly distributed. As said in above posts, the difficulty give the probability to hit a particular prefix after 1 try, nothing more...
63% means that if you make 173346595075428800 tries, you will have 63% of chance to find the desired prefix.

So explaining in the simplest understandable way:
115792089237316195423570985008687907852837564279074904382605163141518161494336 - the size of the entire BTC range
173346595075428800 means as if every "173346595075428800" of spaces appears the prefix searched, but they are not evenly distributed across the full range (i.e. that I can search 10x the whole "173346595075428800" without finding the solution, and searching the 11th range I will find solutions eleven)?

Yes!
