Mosaic graphics:

Regular plane division is called mosaic, and mosaic graphics are the arrangement of closed graphics, with no overlap and no gaps. Generally speaking, the basic unit of mosaic pattern is polygon or similar conventional shape, such as square tiles commonly used on the floor.

Escher used these basic patterns in his mosaics. He used reflection, smooth reflection, transformation and rotation in geometry to obtain more diverse patterns. He also twisted these basic patterns into animals, birds and other shapes. These changes have to be symmetrical three times, four times or even six times to get the mosaic pattern.
