comment Why the strange limit?
@Graumagier, make that an answer so I can sign off on it.

@PatrickStevens, very nice!

@VividD, see my update for possible solution.

comment Infinite product for Zeta[2]?
@Dr.WolfgangHintze, Thanks for the heads-up re: $s.$ The interesting pattern is that the prime product uses primes only. We use multiples of $4,6$ which are the mid-points where odd primes can occur. As soon as I get my activation code for Mathematica later today, I plan to look at both functions to see the differences/commonalities. It might not be special?

comment Infinite product for Zeta[2]?
@Dr.WolfgangHintze, It's the Euler product using multiples of 6.

+1 for nice plot. I've learned something new.

comment Infinite product for Zeta[2]?
@Dr.WolfgangHintze, A few years ago I found a product that produced $\frac{\pi}{3}$ using multiples of $6.$ Yesterday I decided to square it and insert something to multiply by $\frac{3}{2}$. It seems to work.

comment Possible improvements to this Syracuse (3x+1)/2 graph?
I like it. My new version is based the prism I use in my proofs. So, I think I will be using both methods for the graphing part of the paper. Should I delete the temporary answer now?

comment Possible improvements to this Syracuse (3x+1)/2 graph?
I like your answer, but for my paper I have to describe it from a different perspective which is why I posted the temporary answer. Let me know if you see anything that is awry. I'll delete it in a few days. Thanks for everything. This goes for @Guesswhoitis., too.

comment Why can Reduce solve for Integers but not for Reals?
@Mr.Wizard, I wondered that too. I usually use FullSimplify after the Reduce to use the code elsewhere.

+1, FullSimplify is just the ticket!

comment Why can Reduce solve for Integers but not for Reals?
@ChipHurst, I didn't know the default domain, however using Reals also doesn't work.

comment Question about a catalytic equality?
+1, I had missed the simplification until you showed the last line. Thanks.

comment Is there a notebook to create entries for OEIS?
@belisarius, it's probably a variation of the one in my edit above. If someone answers, I can check it off; or I could delete the OP. What do you think?

comment Is there a notebook to create entries for OEIS?
@Mr.Wizard, I think it set up all the sections on OEIS in their proper formats. I'm not sure if it provided a method to post on OEIS.

comment Can degenerating Nicomachus' triangle down to $0$ area by using `Graph` be done?
@RahulNarain, That looks like a viable approach. Thanks.

@belisarius, I have posted the image. It's close to what we should get.

comment Can degenerating Nicomachus' triangle down to $0$ area by using `Graph` be done?
@belisarius, When triangle 1-2-3 is graphed we get a triangle with uniform edges. If we make the edges equal to the differences, the triangle loses its shape and becomes a straight line 1-2-3 with an edge back from 3-1.

comment How can we get this infinite prism lattice to look more like `PolyhedronData[{“Prism”, 3}]`?
Exactly what I need. Thanks.
