For Cartesian squares in category theory, see. In mathematics, specifically set theory, the Cartesian product of two sets A and B, denoted AB, is the set of all ordered pairs (a, b) where a is in A and b is in B. (Product) Notation Induction . The input set can be specified in the standard set format, using curly brace characters { } on the sides and a comma as the element separator (for example {1, 2, 3}) and in a non-standard set format (for example [1 2 3] or <1*2*3>). Instead, the categorical product is known as the tensor product of graphs. The other cardinality counting mode "Count Only Duplicate Elements" does the opposite and counts only copies of elements. For any given set, the cardinality is defined as the number of elements in it.
