👉 Repetends is a mathematical concept in combinatorics and graph theory. It refers to a sequence of elements that repeats indefinitely, such as "abcd" or "abcde". In graph theory, it is used to describe paths between vertices in a graph. The definition of a repetend can be extended to include more complex structures, such as binary trees or graphs with multiple cycles. In these cases, a repetend is defined as any cycle that contains at least one node but does not have
