A complemented lattice is a type of lattice in which every element has a complement. Specifically, a lattice \( L \) is a complemented lattice if, for every element \( a \in L \), there exists an element \( b \in L \) such that: 1. \( a \vee b = 1 \) (the join of \( a \) and \( b \) is the greatest element of the lattice, often denoted as \( 1 \)) 2.
