### Re: Problem 371

how is "expected to win" defined exactly? the chance of seeing a pair must be >50%? Expanding on Animus ' response, "expectation" here is defined in the statistical sense. The wikipedia page is a good place to start if you haven't encountered the concept previously. I do remember it being a bit con...

"First, they agree on a positive integer n, and

So for n = 1, they start by writing "1". Then it's Oscar's turn, but his only option is to write another "1", leaving an even number of 1s on the board.

### Re: Problem 618

Your answer for $S(21)$ is wrong- the correct value is roughly a quarter of yours. If it helps diagnose the bug, there are $30$ distinct numbers which have a prime factor sum of $21$; the lowest is $38$, and the largest $2187$.

### Re: Problem 652

Can we assume this conjecture for the given N=10^18? If making this assumption leads you to a different answer, then you've disproved the four exponentials conjecture! So either it's fine to assume the conjecture holds for larger N, or you settle a currently unsolved problem in number theory. Eithe...
