Lists and Sequences

Abstract

A list in GeoGebra is an ordered set that can contain repetitions.  For example, {1,2,3} and {2,3,1} are both lists, but they are not equal since the elements of the list (namely 1, 2, and 3) are in a different order.  Note, too, that lists need not be lists of numbers. Instead, they can contain other objects such as numbers, coordinate pairs, polygons, and conics. We explore several examples in the following paper.
