Talk:Coset Product is Well-Defined

Coset product should be distinguished from subset product by separate notation (at the moment both are denoted with $\circ$) because this result is established by Coset Product Consistent with Subset Product Definition. I'd propose to denote first with $\circ$ and second by juxtaposition; other propositions are warmly welcome! (maybe $\circ$ and $\bullet$ respectively!?) BTW. In some places cosets are denoted like $aH$ and in some places like $a \circ H$, this is little bit inconsistent… joel talk 18:15, 29 December 2012 (UTC)
