align inside gather - does not center properly (AMSMATH/LaTeX)

[porky_...@my-deja.com]

I'm reading 'Math into LaTeX' by Gratzer (3rd edition), and in section
5.6.2 which discusses Split, there is an example of split (and align)
inside a gather environment:
\begin{gather}\label{E:mm10}
\begin{split}
f &= (x_{1} x_{2} x_{3} x_{4} x_{5} x_{6})^{2}\\
&= (x_{1} x_{2} x_{3} x_{4} x_{5}
+ x_{1} x_{3} x_{4} x_{5} x_{6}
+ x_{1} x_{2} x_{4} x_{5} x_{6}
+ x_{1} x_{2} x_{3} x_{5} x_{6})^{2}\\
&= (x_{1} x_{2} x_{3} x_{4}
+ x_{1} x_{2} x_{3} x_{5}
+ x_{1} x_{2} x_{4} x_{5}
+ x_{1} x_{3} x_{4} x_{5})^{2}
\end{split}\\
\begin{align*}
g &= y_{1} y_{2} y_{3}\\
h &= z_{1}^{2} z_{2}^{2} z_{3}^{2} z_{4}^{2}
\end{align*}
\end{gather}

In a book, everything is typeset just fine and perfectly centered.
However I just can't get the same result. 'Split' part comes out fine,
but 'align' part comes out shifted to the right. Now idea what's going
on. Can anyone shed the light?

I'm using MikTeX which I've downloaded sometime early September 2004,
runing on Windows XP. I run 'latex', then 'dvips', and look at the
result with GSView 4.6.
I've tried to run this example in both 'article' and 'book' latex
environments, each time with the same result.

TIA.

(Sorry, example is nicely indented, but somehow when I post it from
Google, all indentation disappears. Boo hoo)

Use aligned instead of align.

Thanks, that worked fine. I probably will be contacting the author of
this book to find out what is the story. Either the statement he
provided as an example wasn't the one he used to typeset, or something
else is wrong.

Thanks again.

You're welcome.

A very good reference is the amsmath documentation. If your install of
MikTeX is complete you already have it. Just open a shell and type
"texdoc amsldoc" to view it. Another very good reference is "Math
mode" written by Herbert Voss, you can find it here:
http://www.perce.de/LaTeX/math/Mathmode.pdf. It covers the amsmath
package in great detail, has a large number of examples and is typeset
nicely!
