👉 In mathematics, a Brattain lattice is a type of lattice that was introduced by J. L. E. Brattain in 1967 as an extension of the notion of a lattice with a binary operation and a unary operation. The idea behind this concept is to provide a way for more efficient computation in combinatorics, graph theory, and other areas where it's necessary to work with sets.
A Brattain lattice is defined by the following properties:
