What does it mean when there are two 1s with a curve over a note?

Question

I have never seen this kind of symbol before and google has failed me.

This notation occurs in Chopin Nocturne Op. 9, No. 1, measure 2 beats 4–6.

It's an 11-tuplet. Like a triplet, but with 11 notes where there would otherwise be 8 (or some other power of 2).

It's also incorrectly notated: the 11-tuplet sign should be on the beam side – PiedPiper Jun 07 '21 at 13:47

According to Wiktionary, the word to denote this is undecuplet or hendecuplet, although there are no articles for those words as of 8 June 2021.
