Its defining feature is an underlying orthogonality that enforces a highly regular and sparse internal structure. This raises a fundamental structural question that has received little explicit attention:</p> <blockquote> <p><em><strong>Why not consider universal non-orthogonal construction while preserving the cardinality $2^k$?</strong></em></p> </blockquote> <p>In this paper, we answer this question affirmatively by exhibiting an explicit non-orthogonal recursive construction.<br>The loss of orthogonality allows for substantially richer local configurations.<br>In particular, the resulting sets may contain desired longer consecutive integer runs than those permitted by the Thue--Morse construction, while still satisfying all moment identities up to degree $k$ and preserving the classical bound $2^k$.</p> <p> <strong>Cite as: </strong> Saša Jovičević (2026), <strong>Non-Orthogonal Universal Construction for the Prouhet–Tarry–Escott Problem</strong>, Zenodo.</p>
