Let A = {1, 2, 3, 6, 12, 18} and R be defined by xRy if and only if x|y.
a) Draw the digraph of R. Below are images you can use to create the diagraph. You may copy/paste the arrow and alter the directions and length as needed.
b) Draw the Hasse diagram of R. Below are images you can use to create the diagraph. You may copy/paste the images and alter the directions and length as needed.
c) Give a subset of B of A that is linearly ordered with respect to R and contains at least three elements.
