More specifically, both of basic element data (figDand figD) have cell data (cell) as the parent cell information, all of basic element data (figDto figD) have cell data (cell) as the parent cell information, the cell data (cell) have two identical cell data (celland cell) as the parent cell information, and the cell data (cell) have three identical cell data (cell, celland cell) as the parent cell information.
