Answer:
Equality 7-2521 is the protagonist's chosen name in Ayn Rand's book "Anthem," which is ironic given that he lives in a culture that suppresses individualism and personal freedom. People in this society are given numbers instead of names, and the idea of "equality" is interpreted to mean that everyone is identical in every manner and that there is no room for individuality or distinctions.
Equality 7-2521, on the other hand, is not satisfied with this way of life and longs for independence and uniqueness, making his choice of name ironic. Equality 7-2521 is distinct and different from other people, which goes against the fundamental concept of "equality" that the society is based on, despite the claim made by the society to promote equality.
