Scientists have shown that solving any Rubik's cube takes up to 20 steps

According to foreign media reports, I believe that many people have played the Rubik's cube, but no one knows what the minimum number of steps of any combination of Rubik's cube is. This problem has puzzled mathematicians for more than three decades, and this minimum reduction step is also known as the "God's number." Scientists in California recently used computers to solve this mystery, researchers proved that any combination of Rubik's cube can be restored within 20 steps, and the "number of God" is officially set at 20.
