The static {ital q{bar q}} potential is measured on 24{sup 3}{times}10, 24{sup 3}{times}12, 12{sup 3}{times}24, and 16{sup 3}{times}24 lattices at {beta}=6.0 with high statistics. Using Wilson line operator-operator correlations, we find {radical}{sigma} /{Lambda}{sub {ital L}}{congruent}77 and {alpha}{congruent}0.58. This new result compares favorably with that obtained from charmonium experimental data, but is significantly different from many previous lattice calculations. Our calculations use a hypercube parallel computer which in its full configuration performs at 0.6 gigaflops on this application.
