Re: Collational formula query

[Donald Farren <p00244@PSILINK.COM>]

TB may be right that you have "blank leaf wraparounds" and that you
have "concealed stubs" that you did not notice.  But since you described
the first two leaves of your book as "preliminary leaves" (therefore
printed, I infer) and since you wrote that "the copy is untrimmed in its
original paper covers, making it easy to see conjugacy, cancels,
etc."--what you described appears to me (I leave to you to convert the
following "in 8s" and "in 4" to superscripts) to be: pi1,2  A-L in 8s
[M] in 4 (-[M]1,2 = pi1,2).
