ReferenceintervalList

<intervalList>

A list of intervals

<intervalList> is a Math component that collects a sequence of intervals.

When creating an <intervalList>, separate items by spaces, not commas. The component will default to displaying the list with commas. (The commas that appear inside each interval — e.g. (-1, 2) — are part of the interval itself, not separators between intervals.)
