The endpoint adjoining the square bracket is known as closed, while the endpoint adjoining the parenthesis is known as open. If both types of brackets are the same, the entire interval may be referred to as closed or open as appropriate. Whenever infinity or negative infinity is used as an endpoint (in the case of intervals on the real number ...
An interval is said to be left-open if and only if it contains no minimum (an element that is smaller than all other elements); right-open if it contains no maximum; and open if it contains neither. The interval [0, 1) = {x | 0 ≤ x < 1}, for example, is left-closed and right-open. The empty set and the set of all reals are both open and ...

The closed-closed template wraps its argument in a left square bracket, right square bracket. These are used to delimit a closed-closed interval in mathematics, that is one which includes both the start and end points. The template uses {} to ensure there is no line break in the expression and format Greek characters better.
