Abstract
Let L be a lattice. For a natural number n we associate a simple graph denoted by T^nL with L^n-{0} as the vertex set and two distinct vertices X and Y begin adjacent if and only if there exists an nxn lower triangular matrix A over L such that AX^T=YT or AYT=X^T, where for a matrix B , B^T is the matrix transpose of B. In ths talk we study some basic properties of T^nL.
