Weiqi consists of 18 1 sunspot and 180 Bai Zi. The chessboard consists of 36 1 intersections of 19 roads. There may be dots, Bai Zi or empty pockets at every intersection on the board of Go, that is, there are three possible changes at an intersection: black, white and empty. It is possible for the two intersections to become the square of 3. The possibility that the intersection of 36 1 has a variation of 3 to the power of 36 1.

The approximate number of Go changes is a positive integer of 173 digits, which is written as 10/72 power in modern mathematics. This is an amazing number. If you use the most advanced electronic computer in the world to calculate, assuming that the computer calculates 65.438 billion times per second, then 654.38+ 0 months can calculate 259 trillion times; 1 year can be estimated to the power of 10/7; 10,000 years can be calculated to the power of 2 1 0; 1 100 million years can be calculated to the 25th power of 10. To complete the change of 10 to the power of 172, the time required can be imagined.
