Abstract
A de Bruijn torus is the two dimensional generalization of a de Bruijn sequence. While methods exist to generate these tori, only a few methods of construction are known. We present a novel method to generate de Bruijn tori with rectangular windows by combining two variants of de Bruijn sequences.

Notes
The last row and column are adjacent to the first row and column respectively.
\(\Pi \) being the rotations on strings of length r
Here we use the variable convention in [4].
i.e. we apply the cumulative rotations on each string.
It is unknown how many de Bruijn families exist.
Recall that i represents \(\pi _i\) etc.
