How can I render the connected sum of $n$ topological spaces (or other quite strange topological operations) in a "product-like" manner? What I'm looking for is writing, for example $ {\Large{*}}_{i=1}^n G_i $ for the free product of n groups. How can I render this with the # operation in topological spaces? (Yes, I'm studying Hatcher's AT...)

1P.S. $\#$ is an operation on manifolds, not arbitrary topological spaces. – 2010-11-07

This question was asked over at tex.se, Define strange operators, with an accepted answer by frabjous:
The
\mathop{..}
command from amsmath makes its argument behave like a "large operator".
with some example code.
