What is the law of octal numbers?

In fact, long ago, the ancients understood the concept of octal, such as gossip. ...

Gossip was originally a symbol of the ancients, but later it was branded as a feudal superstition and became a divination tool. It implies the concepts of binary and octal. The basic elements of gossip are yin and yang, and binary is equivalent to 0 and 1.

In the figure below, a long solid line represents "Yang", and a line broken in the middle represents "Yin", and then three such lines form eight shapes, which is equivalent to three binary numbers representing eight states.

Octal counting, of course, cannot be represented by gossip, and is usually represented by Arabic numerals from 0 to 7.

Octal counting rules:

It consists of eight numbers, namely 0, 1, 2, 3, 4, 5, 6 and 7.
