Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

An equational basis of the lattice variety $$\mathbf{S}\mathbf{P}(L_{4})$$ generated by the finite non-semidistributive lattice $$L_{4}$$ is found in order to establish in a subsequent paper a duality result for the category of bi-algebraic lattices belonging to this variety.
