Title: Puzzle 66 prediction
Post by: pbies on January 27, 2024, 06:08:12 PM
Can you guys share narrowest prediction ranges for puzzle 66 integer private key?

I have much computer power to do a search, so we could share the prize. I can try some ranges...

I have a silly script that tries to predict the challenge keys. I like to toy with this stuff.

If I pass it the sequence of known keys from #1 to #64, this is the prediction for #65:

Prediction: 3.05208467e+19 -> 1A78FD45E05A73800

Now passing it the sequence from #1 to #65:

Prediction: 4.73075146e+19 -> 290860DE1FB9B1000

I found nothing from -1M to +1M for this value.

EDIT:

The space for puzzle 66 is 0x3FFFFFFFFFFFFFFFF-0x20000000000000000 which gives in decimal 36 893 488 147 419 103 231.
