Summary
Illustration of the m=1,2,3, and 4 tokamak plasma cross section shape perturbations: m=1 is the Shafranov shift, which displaces the center of a flux surface from the nominal geometric center of the LCFS, m=2 is elongation, which stretches the plasma vertically, m=3 is triangularity, which is increased by pulling the X-points to smaller R, and m=4 is squareness.
