Yes, it's an error. The list is supposed to be the same as in ISO C.

There is only one edition, although there have been many printings. Each
new printing has corrected minor errors missed in earlier printings.

When reading my copy of the AC++RM again,
I noticed something I suspect to be an error.
Can anyone confirm or deny the following:

In the chapter about trigrams (?) there
is a list of all defined trigrams
but ??< and ??> are not on the list.
The example program below the list
uses ??< for { and ??> for }.
Therefore the list is not
complete and should contain ??< for {
and ??> for }

The copy of the AC++RM I have is the first edition.

Greetings from Paul.

What you are referring to are called "trigraphs".

The copy of the ARM I have lists the full set of trigraph
sequences (sec 16.2, p. 371).  I've duplicated it here for
your convenience, where the trigraph is followed by the
equivalent character:

  ??=  #        ??(  [       ??<  {
  ??/  \        ??)  ]       ??>  }
  ??*  ^        ??!  |       ??-  ~

I hope this helps (or at least was an answer to your
question).
