Will fix it as suggested below when seq appears in OEIS.

The anchor brings you to the green headline
(The steadily growing "Algorithms for programmers" text (the fxtbook))
near the bottom of the page.
The top line shown with your browser will be before
the point in question with practically all window
geometries.  I added the word "fxtbook" to the
(green) headline to make it more obvious.

I'll add the section headline.
Adding section number and page would be stupid because
these _do_ still change.

Currently:
section 1.19 ("Invertible transforms on words") on page 42ff.
seq appears on page 44 ("Fixed points of the blue code")

When the first edition is out, I'll go through all
my OEIS entries and add more precise references.

I see.
For me "hard to follow up" is synonymous for "annoying".
I'll fix it.

I always test my link(s).  There is no technical fix for that anchor
issue.  If browsers would somehow highlight the referenced area (as
dvi viewer do with TeX source specials) that problem would go away.

I have the book.
The fxtbook also has quite a few bit-magic goodies
(chapter 1: "Bit wizardry", pp.3ff).
Some of the tricks are new to my best knowlegde.
That chapter (and the rest of the book) has many
references to the OEIS (search for "OEIS" with your
dvi/pdf viewer!).

Thanks for your answer!
