 Congruence lattice problem

The Congruence Lattice Problem is a problem in the field of mathematical logic, specifically in lattice theory and universal algebra. It involves understanding the structure and properties of congruence lattices associated with algebraic structures such as groups, rings, and lattices. In more formal terms, for an algebraic structure \( A \), a **congruence** on \( A \) is an equivalence relation that is compatible with the operations of the structure.
