@MartinR Even if that's the case, the situation is not exactly clear-cut. MathJax handles Unicode characters in Mathe Mode just fine (this is different from LaTeX). I would agree that avoiding to use them is better for searching but I don't think this influences how math formulas are displayed.

Meta: θ vs. $\theta$ - What is preferred? Unicode or MathJax? (and other posts linked there) and Would HTML/Unicode formatting cause troubles? (This one seems to be more about html. I will add list of linked posts anyway.)

new-tag A new tag lyndonwords was created by GA316. Rename to lyndon-words? Or remove completely as too specific?

Q: Number of Lyndon words of 4 alphabets, One alphabet labeled, the other 3 unlabelled.

1) In the following OEIS Sequence, what is the meaning of One alphabet labeled, the other $3$ unlabeled? The number of Lyndon words (aperiodic necklaces) with $4n$ beads of $4$ colors, $n$ beads of each color. One color labeled, the other $3$ unlabeled. $1, 52, 5133, 656880, 97772875, 1603...

Lyndon word

In mathematics, in the areas of combinatorics and computer science, a Lyndon word is a nonempty string that is strictly smaller in lexicographic order than all of its rotations. Lyndon words are named after mathematician Roger Lyndon, who investigated them in 1954, calling them standard lexicographic sequences. Anatoly Shirshov introduced Lyndon words in 1953 calling them regular words. == Definitions == Several equivalent definitions are possible. A k-ary Lyndon word of length n > 0 is an n-character string over an alphabet of size k, and which is the unique minimum element in the lexicographical...

I see that the same question was now asked also on MO - where the tag lyndon-words already existed.

@MartinSleziak @AnyoneElse I seem to recall some advice on tagging which (essentially) says that you should use tags which narrowly explain what your question is about, and not to explain where your question might be applied. For example, I might have a question about the $p$-adic numbers, but because I view them as a metric space and don't care so much about the algebraic structure, the tag fields would likely be inappropriate.

I ask because I think that this question (which is a perfectly fine question, I think) does not seem to have anything to do with fractals, except by way of application.
