What does "x+z" with the rediculas rhyming word "geschmäht" in the original version http://www.zeno.org/nid/20005258049 mean? I think x could be an integral multiple of pi and z a second integer. Then one has a torsion free abelian group. As the irrationality of pi was not yet known in 1750 the question was perhaps whether the rank of this group is 1 or 2.
