Yes. Theoretically, you need at least 1TB. I've never tried more than 60. Anything around 300GB is considered a baby table. I don't have time to wait for a bigger one to be generated.

Why are you publishing all the scripts from before now?
Because it's a dead end. Game over. There's no point in hiding any more scripts for the puzzles - whether they're useful or not. For Puzzle 69, you're over 2,500 GPUs. For Puzzle 71, over 3,000.
Try to see deeper, even if you was eaten by somebody, you have at least two ways:)
First decision - Increase speed of brooteforcing twice from present speed. And amount of GPU will be less than you think.
Second decision - Invest more for GPU rent or just buy dozens of rtx5090. After success or fail you will sell this stuff.
My opinion, that this is only fun game with money prize, not more. This is a brain massage, not more, for me:)
