Pennsylvania Route 343 highway remained intact for another seven years, and in 1970, PA 343 was realigned for the final time, this time onto its current alignment. The northern terminus is now at a partial interchange with I-78. Pennsylvania Route 343 Pennsylvania Route 343 (PA 343) is an route between Lebanon and Fredericksburg in Lebanon County, Pennsylvania. It begins at PA 72 and ends at Exit 6 of Interstate 78 (I-78). PA 343 heads mostly through urbanized areas near Lebanon before continuing into rural areas further north. There is a concurrency with U.S. Route 22 (US 22) near the northern terminus. PA 343
Partial cube root vertex "r" for the tree, arbitrarily, and label each vertex "v" with a string of "m" bits that has a 1 in position "i" whenever edge "i" lies on the path from "r" to "v" in "T". For instance, "r" itself will have a label that is all zero bits, its neighbors will have labels with a single 1-bit, etc. Then the Hamming distance between any two labels is the distance between the two vertices in the tree, so this labeling shows that "T" is a partial cube. Every hypercube graph is itself a partial cube, which can be
