See those two pins? Well today I'm going to... stick them in you.


Ok, let me come clean: Mr.Wizard is actually an alias of mine... I'm glad I can finally confess. ― Sjoerd C. de Vries

No, I'm Spatac... I mean, Mr.Wizard! ― R.M

I'm Mr.W, and so's my wife! ― acl


@Spartacus, it was not fixable. ― rcollyer

check again; I just fixed it. :-p ― Spartacus

It's not that easy to do the untangling even manually though. – Szabolcs

Maybe you could turn it into a puzzle and let other people do the untangling :-) – Heike

I could make a web based game, and feed all my graphs to the visitors.
SE is a big game, isn't it? :D – Szabolcs

I was tempted to edit your title: "Do rules rule?" But my nose is still bleeding as a result of a limerick. – belisarius


No, but they nowadays let me turn off the lights at night; 24 hours of fluorescence was really starting to make me feral. Brett says I should also mention the tip jar... – Daniel Lichtblau Mar 13 '12 at 20:48

comment Can Mathematica delete some of the 0's from a list?
This kills leading zero as well, which it should not, and it doesn't work with integers larger than 9. This solves both problems and it's shorter: StringTrim[ToString[list], ", 0" ... ~~ "}"] <> "}" // ToExpression :^)

Note that this only works because by default the first pattern is treated as Shortest. In reverse order this fails: {0, 0, 0, 1, 2, 3, 0, 0, 4, 5} /. {0 ..., a___} :> {a}. Adding a Shortest or Longest corrects the problem: {0, 0, 0, 1, 2, 3, 0, 0, 4, 5} /. {Longest[0 ...], a___} :> {a}

@Kuba That's multiplication. I thought this question was about the additive rule?

If you are able to include code that generates an example polynomial that produces the recursion limit warning you may get better answers sooner, as it makes it less work to answer.

comment Toolbars in Mathematica
@Marius How did you install this palette? Does it appear in the Palettes menu? If so please try opening the palette using that menu, then close Mathematica without first closing the palette. When you restart it should automatically open. If it does not let me know.

SparseArray[#, Automatic, 0] is somewhat verbose; Automatic and 0 are the defaults so you need only SparseArray[#].

Note: the "big-list" tag was created for a different purpose as noted in its tag wiki. I removed it from this question. Given the confusion it seems to cause it may be removed entirely in the future.
