Your argument On the other hand, all the terms of the product are less than 1.
- What does the $\prod$ symbol mean? - Mathematics Stack ExchangeThe symbol $\Pi$ is the pi-product. It is like the summation symbol $\sum$ but rather than addition its operation is multiplication. For example, $$ \prod_{i=1}^5i=1\cdot2\cdot3\cdot4\cdot5=120 $$ The other symbol is the coproduct.
