What does it mean to see four or six in the four seas and count three to six?

"Looking at the world from four to six, three numbers determine six" is an ancient mathematical derivation method. This is a way to predict the possible outcome of something in the future. "Four Seas and Four Six Views" refers to all things in the world, and "Four Six Views" refers to four combinations: six hexagrams (full yin), six hexagrams (full yang), four hexagrams (less yin) and four hexagrams (less yang). In the traditional Yi-ology, six hexagrams is a way of divination. You can get a divination image by tossing a copper coin or calculating the changes of six hexagrams with six simple cards. "Three numbers determine six" is to calculate the changes of these six hexagrams, divide them into three groups to get six numbers, and then infer the possible results through the combination of these six numbers. Specifically, for each change, the positive value is 1 and the negative value is 0, and then these six arrays are combined into three binary numbers. By converting these three binary numbers into decimal numbers, a numerical value with the range of 1-64 is obtained, corresponding to one of the 64 hexagrams, so as to find its symbolic image. This method mainly relies on the explanation of mathematics and hexagrams, and is considered to reveal some possible situations or results.
