Cyclic difference matrix conjecture for the Fibonacci-like partition construction

About 1 year old · traced to

Let qi,j=qi,j[m,n]q_{i,j}=q_{i,j}^{[m,n]} be the non-negative integers obtained in Algorithm; these integers are independent of mm and nn. For each i≥1i\geq 1, consider the sequence {qi,j}j∈Z≥0\{q_{i,j}\}_{j\in\mathbb Z^{\geq 0}}. Cyclic difference matrix conjecture. For every i≥1i\geq 1, the sequence {qi,j}j∈Z≥0\{q_{i,j}\}_{j\in\mathbb Z^{\geq 0}} is a permutation of Z≥0\mathbb Z^{\geq 0}, and for every pair of natural numbers i1<i2i_1<i_2, every integer appears exactly once in the sequence

{qi1,j−qi2,j}j∈Z≥0.\{q_{i_1,j}-q_{i_2,j}\}_{j\in\mathbb Z^{\geq 0}}.

If true, this would give the desired countably infinite analogue of a difference matrix over the infinite cyclic group, whose additive group is the group of integers. The claim is presented as a conjectural generalization of an earlier theorem; no resolution is supplied in the given text.
