Fibonacci-4, also known as the黄金分割数列, is a series of numbers that is commonly found throughout nature, art, and architecture. It is a sequence of four numbers, with each number being the sum of the two preceding numbers. The sequence starts with 1 and 2, and the subsequent numbers in the sequence are 3, 5, 8, 13, 21, 34, 55, and so on.

The Fibonacci-4 sequence is named after the Italian mathematician Leonardo Fibonacci, who first discovered the sequence in the 13th century. He believed that the sequence had mystical or divine origins, and that it was a representation of the divine ratio between the universe and its inhabitants.

The numbers in the Fibonacci-4 sequence have been found in various forms and in different cultures, indicating that it is a universal phenomenon. For example, the sequence appears in the arrangement of leaves on a stem, the branching of trees, the branching of rivers, and the configuration of the stars. It is also present in the design of many architectural and artistic works, such as the famous equation \"phi\" (1+1) and the proportion of the golden angle, which is believed to be the most aesthetically pleasing angle.

The Fibonacci-4 sequence has also been studied in the context of mathematics, and it has been found to have a number of interesting mathematical properties. For example, the sum of the first four numbers in the sequence is equal to the sum of the last four numbers, and the ratio of any two adjacent numbers in the sequence is equal to 1.582.

In conclusion, the Fibonacci-4 sequence is a phenomenon that has been found in nature, art, and architecture, and it has interesting mathematical properties. While its origins are not clear, it is believed to represent a fundamental aspect of the universe, and its presence in different cultures and contexts indicates its universal nature. The study of the Fibonacci-4 sequence has, therefore, become an important area of research, with applications in various fields, including mathematics, physics, and architecture.
