     We also have a few basic set operations, for example the union of
     two or three sets: $\union{A}{B}$, $\unionthree{A}{B}{C}$. And of
     course with union comes intersection: $\intersect{A}{B}$,
-    $\intersectthree{A}{B}{C}$.
+    $\intersectthree{A}{B}{C}$. We can also take an arbitrary

+    $\unionmany{k=1}{\infty}{A_{k}}$ or
+    $\intersectmany{k=1}{\infty}{B_{k}}$. The best part about those
