In chapter 4, How is the renaming of the characters significant? What are their new names and why?

THere are really only two characters that chapter four leads us to, 7-2521 and the Golden One. The setting of Chapter Four is the hedge separating the Peasants' fields and the road leading to the city, on a particularly hot and oppressive day. Ironically, the heat that takes away the spirit and energy of the other women in the field allows the Golden One to escape the repressive laws and speak with Equality 7-2521 without being overheard. The hedge is a symbol of separation, representing the rules that prevent the two lovers from permanently joining, but it also represents the border between the city and its outer limits. As Equality 7-2521 approaches the border to talk to the Golden One, he also approaches the figurative border that will eventually lead to his break with his society.
