@MartinSleziak Indeed I'm counting 29 questions including the word "polyomino", so creation of this tag seems to make sense.
I will add a link to the search, which returns 29 questions - as you said.
@YCor Do you think that it is worth bumping some of older questions by adding this tag? Maybe if we look among the ones which have high score?
Naturally, some of the questions contain the word - but it is not the main topic, so adding the tag would not be suitable there. Such as this one - the word is only mentioned there tangentially: Cool problems to impress students with group theory.

Q: fast algorithm for computing certain signal transformations

RamiLet $f,g,h:\mathbb Z\to\mathbb C$ supported on $[-n,n]$.  For $\tau\in \mathbb Z$, let $sh_\tau   f$ be the shift of $f$ by $\tau$ (i.e. $(sh_\tau f)(t)=f(t-\tau)$). Define $$k(\tau  )=||((sh_\tau f )g)*h||_2$$ I am looking for a fast way to compute $k(\tau)$ for all relevant $\tau$. By fast I me...
