Beaf number array is a mathematical structure proposed by John Conway, which is used to describe the evolution of a series of numbers. In Conway's chain arrow representation, each number points to the next number with an arrow, forming a chain structure. For the array of beaf numbers, we can represent each number as a node and connect them with arrows. For example, if the number 1 points to the number 2 and the number 2 points to the number 3, and so on, we can express it as 1→2→3.
