What is the number of the creation of heaven and earth in the book of Hutuluo?

The number of generations of heaven and earth in Hu Luo Shu is calculated according to the principle of coexistence of gossip, yin and yang and five elements. Among them, the number of days is obtained by adding three numbers of yin and yang, the rank is obtained by adding four numbers of yin and yang, and the number of generations of heaven and earth is obtained by multiplying two numbers. The specific algorithm is: number of days =2+6+7= 15, number of digits =8+3+4+9=24, number of generation of heaven and earth = 15×24=360.
