I am new to this forum.

I have a question:

A relation can be subset of some other relation?

For example? I have the relations

X: A <---> B

Y: B <---> C

Z: A <---> C

X relational composition Y can be a subset of Z (if Z contains all the pairs of the composition)

Thanks in advance for your help
