How does one know that the theorem itself will be small?

Would a proof that no such 4-tuple $(a,b,c,d)$ exists amount to a proof of the continuum hypothesis?

comment Number of length-n paths in a graph with a fixed start vertex
I didn't know that (well, I thought I did, but it's no use if you don't remember on time!) Thanks, I'll make sure to keep that in mind.

comment It is easy to show that $S_m=\sum_{n=1}^\infty \frac{n}{2^n + m}$ converges for any natural$\ m$, but what is its value?
It's a graph of $S_m$ vs. $m$.

@djechlin I agree about that. I'm wondering about how it would be affected if the 2 in the denominator were changed.

The graph is really, really interesting, though: imgur

Partial sums? No, I've only done infinite sums (that is, correct to $10^{-8}\%$).

A quick Python script says that $S_m$ tends to $0$ as $m$ increases, but that is obvious.
