Can anyone decrypt the following:
 122, 151, 164, 175, 184, 203, 221, 272, 278, 287, 323, 356

Some background: This sequence comes from Denning's great cryptography
book that has been refered to a couple of times earlier in the
newsgroup.  On pages 122, 151, ... instead of having a normal page
headnote, reminding the reader about the topic of the chapter, she has
the string ``ABFDEFGHIJKLMMNOHPP''.  Surely this can't be accidental.
This sequence of page numbers must have a meaning.

First attempt: Earlier in the book, Denning discusses how the string
``ABFDEFGHIJKLMMNOHPP'' arose in connection to the Beale Ciphers.  In
one Beale Cipher, the number X should be replaced by the first letter
of the Xth word of the Declaration of Independance.  Does anyone have
an on-line version of the DOI, so that we can check if that is how to
decrypt the above string?

If this doesn't work, does anyone have any other ideas?
