# Talk:Regular set function

From Encyclopedia of Mathematics

## Possible misprint

In the sentence "Such approximation properties imply usually that for a generic set $C\in \mathcal{A}$ there is a set $A\in \mathcal{A}$ such that $|\mu (C\triangle A)|$ is small." is the first occurrence of $\mathcal{A}$ a misprint for $\mathcal{C}$? In other words, should the sentence begin "Such approximation properties imply usually that for a generic set $C\in \mathcal{C}$ there is a set $A\in \mathcal{A}$ $\ldots$"?
