Hello,

I am fairly new at this and doing it as a hobby. I am not familliar

with Grammers but this looked like it was mistyped. Please correct me if I

am

wrong.

On Page 95 at the top.

"3. Suppose r and s are regular expressions denoting the languages L(r)

and

L(s). Then,

<Snip>

c) (r)* is a regular expression denoting (L(r))*.

d) (r) is a regular expression denoting L(r). Footnote"

Footnote: This rule says that extra pairs of Paren may be placed aroung

regular expressions if we desire.

Shouldn't the Footnote go after c and not d? I only posted because this

troubled me and I saw others post Errata for the book on here. Thank you.

Josh
