In the document "Using TeX Notation", there are many examples of a code for displaying mathematical notations.

There is a suspicious correspondence of a code with a displayed notation, in the section "Delimiters and Maths Constructs".

```
(code)
````\}`

⇒ (displayed as) \(x |\}\)

It is necessary to be corrected as

```
(code)
````x \}`

⇒ (displayed as) \(x \}\) .
