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 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.

@ssolver, for example: (your dependency here) && at the beginning of the statement. good luck!

comment Solve within a range?
@ssolver, perhaps you need Clear[x,y,z,kp]. Copy the first statement and remove Full and evaluate and you should get my edit result.

comment Solve within a range?
@ssolver, I took your statement and added the conditions from the 'Where' and did the Reduce[FullSimplify which gave us the next box. The part to the right of kp== is what I plotted.
