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!

@ChipHurst, I didn't know the default domain, however using Reals also doesn't work.

+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?

@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.

I see pyramid on left, pyramid hole on right. I don't see a triangle.

comment Using a variable for two different purposes
+1, another fine answer. I'll play with it for a few days before I accept anything.

A003814 == (j = Table[n, {n, 1, 10}]) works!

I tried it and it's getting closer. It finds the OEIS page. I'm still playing with it.

Assignment (=) doesn't work. This does work A003814 == Table[n, {n, 1, 10}] except the hyperlink keeps the entire string so doesn't find anything. So the StringJoin should truncate at 7 characters.

+1, looks promising.

comment Solve within a range?
@ssolver, for example: (your dependency here) && at the beginning of the statement. good luck!
