Clojure Brain Teasers: Puzzle 6 Page 26

In the paragraph:

“There are fundamentally three kinds of Clojure collections for the purposes of equality—sequential, set, and map. Any collection within one of these partitions will compare equal to another collection within the same partition if it contains the same elements.”

I find the use of the word “partition” confusing.

What’s a partition, and what do partitions have to do with comparing collections?

“Partition” here is just the word to mean that the space of collections is divided into partitions. This is the canonical term for this in the Clojure reference material.
