Paragraph 4 |
There is a section of text that
did not print. The paragraph should read "First, we note that all translations in $\mathcal{T}$ must be generated by integer combinations of $v$ and $w$. For suppose $T_z$ was a translation with $z$ not an integer combination of $v$ and $w$. The two vectors $v,w$ define a parallelogram in the plane and the set of all integer combinations of $v,w$ will divide up the plane into congruent parallelograms." |
