I am looking for a "big" version (sum-class symbol) of the ш symbol (shuffle product). I only found a binary version. Any ideas?

You could compose your own operator... –  Werner Jun 26 at 2:05

Just scale it.

enter image description here

\documentclass{article}

% large ops, copied from shuffle font package
\DeclareFontFamily{U}{bigshuffle}{}
\DeclareFontShape{U}{bigshuffle}{m}{n}{
  <5-8> s*[1.7] shuffle7
  <8->  s*[1.7] shuffle10
}{}
\DeclareSymbolFont{BigShuffle}{U}{bigshuffle}{m}{n}
\DeclareMathSymbol\bigshuffle{\mathop}{BigShuffle}{"001}
\DeclareMathSymbol\bigcshuffle{\mathop}{BigShuffle}{"002}

% binary ops, for comparasion only
\usepackage{shuffle}

\begin{document}

\[
  a\shuffle b, x \cshuffle y
\]

\[
  \bigshuffle_i a_i, \bigcshuffle_{j=1}^n x_j
\]

\end{document}
