How to generate the following symbol(s) in book class?

Question

Is it possible to generate symbol(s) like to following in book-class

The image has been produced by the following code,

\documentclass{article}
\usepackage{kpfonts}

\begin{document}

$\varprod_{i=1}^n A_i$

$$\varprod_{i=1}^n A_i$$

\end{document}

but I don't want to use kpfonts.

Answer 1

Other fonts

Package mathabx

\documentclass{article}
\usepackage{mathabx}
\begin{document}
\centering
$\bigtimes_{i=1}^n A_i$
\[ \bigtimes_{i=1}^n A_i \]
\end{document}

Packages txfonts/pxfonts

\documentclass{article}
\usepackage{txfonts}
\begin{document}
\centering
$\varprod_{i=1}^n A_i$
\[ \varprod_{i=1}^n A_i \]
\end{document}

Package MnSymbol

\documentclass{article}
\usepackage{MnSymbol}
\begin{document}
\centering
$\bigtimes_{i=1}^n A_i$
\[ \bigtimes_{i=1}^n A_i \]
\end{document}

Import math characters

The packages listed in the previous section also change other math symbols. But it is also possible to use math symbols of other fonts by defining math alphabets. However, keep in mind that the number of math alphabets is a limited resource.

\varprod of kpfonts

\documentclass{book}

% Use \varprod of package kpfonts
\DeclareSymbolFont{KPlargesymbolsA}{U}{jkpexa}{m}{n}
\SetSymbolFont{KPlargesymbolsA}{bold}{U}{jkpexa}{bx}{n}
\DeclareMathSymbol{\varprod}{\mathop}{KPlargesymbolsA}{16}

\begin{document}

\centering
$\varprod_{i=1}^n A_i$

\[\varprod_{i=1}^n A_i\]

\end{document}
