A **lattice** \(\Lambda\) is a collection of vectors that can be constructed by adding integer multiples of two (linearly independent) basis vectors:
\[\Lambda = \{ n\vec a + m\vec b\ |\ n, m \in \text{IN} \}.\]
Consider the lattice generated by the basis vectors \(\vec a = (2, -1)\) and \(\vec b = (8, 3)\), i.e.
\[\Lambda = \left\{ \left(\begin{array}{c} 2n + 8m \\ -n + 3m \end{array}\right)\ |\ n, m \in \text{IN}. \right\}.\]
Which of the following set of basis vectors \(\vec a', \vec b'\) describes the same lattice?
