Q: Remove the spaces from the following sentence: The third lecture gives the essential steps in the enumeration of the seventeen space-groups of two-dimensional crystallography ... [In the fourth lecture he] shows how the special theory of relativity is essentially the study of the inherent symmetry of the four-dimensional space-time continuum, where the symmetry operations are the Lorentz transformations; and how the symmetry operations of an atom, according to quantum mechanics, include the permutations of its peripheral electrons.
