self doubt #equivalence class

Question

for a given relation and set how to find Equivalence class.

for example if I take set S={1,2,3,4} and equivalence relation R= {(1,1), (1,2), (2,1), (2,2), (3,3), (3,4), (4,3), (4,4)}.

find equivalence class for the relation?

Comments

equivalence class

[1] = {1,2}

[2] = {1,2,}

[3] = {3,4}

[4] = {3,4}

equivalence partitions are  2

P1 = {1,2}  p2 = {3,4}

Magma equivalence partitions are distinct equivalence classes?
