I'm wondering what the preferred notation is for denoting a (countably) infinite product measure for which all marginals are equal to some given probability measure $\mu$. Is it common, for example, to write $\mu^{\infty}$? Are there any other reasonably concise ways that this is done? Thanks in advance.

${}{}\mu^{\otimes\mathbb N}$
