Explanation

Sometimes shapes are used to represent the omission of a number, variable, operation, or sign of comparison. The most common shapes used for this are the triangle, circle, and square. However, other shapes may also be encountered. The shape indicator is dots one-two-four-six. A triangle is represented by the shape indicator followed by a lowercase letter t. A circle is represented by the shape indicator followed by a lowercase letter c. A square is represented by the shape indicator followed by a Nemeth four (dots two-five-six).

In these cases, the shape is spaced based on the item they represent.
