Combinatorics Terminology: Finite Sequence of Symbols Modulo Reversal
$begingroup$
Simple question, hard to Google:
What do we call the combinatorial species that associates a set of symbols with linear configuration or chain of symbols without a designated first or last symbol? Or the combinatorial species of finite sequences modulo identification under reversal?
Edit: a linear necklace? A bar?

Maybe this helps: https://en.wikipedia.org/wiki/Necklace_%28combinatorics%29.
In short:
A finite sequence up to rotational invariance is called "necklace". A finite sequence up to rotation and reflection is called a "bracelet".
