| Abstract: | We present diagrammatic schemes characterizing congruence 3-permutable and distributive algebras. We show that a congruence 3-permutable algebra is congruence meetsemidistributive if and only if it is distributive. We characterize varieties of algebras satisfying the so-called triangular scheme by means of a Maltsev-type condition. |
| Keywords: | congruence distributivity congruence 3-permutability congruence n-permutability diagrammatic scheme the triangular scheme |
