You'd better upgrade Prime95 to the latest version of 30.8 to enjoy the P-1 speedup.

The best way to win is to run the lottery and sell tickets.

Or, if there are oppressive laws in your area that forbid you doing that, then rig it in your favour, or bribe the programmer, or similar.

This brings to mind a criminal case I'd heard about some years back.

<google google>

Found it. The following news story from January 2022 is about the case.

Lottery scam's alleged mastermind is paroled after 4 1/2 years in prison

Quote:

<snip>
The Iowa Board of Parole has approved the release of Eddie Tipton, the former information security director of the Multi-State Lottery Association based in Urbandale. Tipton was arrested in 2015 and accused of installing computer code on lottery computers that allowed him to predict the winning numbers.

His efforts to rig the drawings were uncovered after Iowa Lottery officials grew suspicious over an anonymous attempt to claim a $16.5 million Hot Lotto jackpot. They eventually linked Tipton, his brother, Tommy, and a longtime friend, Robert Rhodes, to suspicious winnings claimed in five states.

ECM found a factor in curve #27, stage #2
Sigma=8224392319313050, B1=50000, B2=117709515.
M2223281 has a factor: 270242207010285199568677607 (ECM curve 27, B1=50000, B2=117709515)

The group order calculator on factordb seems to be down right at the moment, but this was about 3 curves from finishing t25.

1 down from 2.22M, 11 more to go :)
