should stop there though.

That’s the point of this fake user. To get as many people as possible to leave this topic, so only Digarans remain in it Grin

Oh I meant the discussion between him and I.
I’ll stay here for other people

Which puzzle numbers have you solved? Did you work on them solo or in a pool? And how much time did you spend on all of them?

I suggest you read my post history it will be simpler.
I solved 67 and 68. I was managing operations but got funding from about 20 people. So it was essentially a centrally managed private pool.

Cool! Have you decided to stop here or are you ready to keep developing your strategic skills?

I stopped there. 71 is not worth it from a cost / risk / reward perspective

What computational power do you have at your disposal, and by how much would the range need to be reduced to make it profitable?

It’s variable since we rent the machines. But we peaked at tens of thousands of GPUs
71 is profitable at only a quater of the problem size.

Am I right in thinking that a quarter of the range corresponds to the maximum 21-digit number, and it's no more than 590295810358705651712?
