The Small Davenport Constant of the Heisenberg Group of Order 125
Godara and Sarkar proved for the exponent- Heisenberg group and posed for every odd prime , leaving open. The paper settles the first open case, , the upper bound reducing to a finite spread bound verified by exhaustive search and independently reproduced.

What was actually shown
Settles the case p=5. The posed formula for every odd prime remains open.
What the AI did
An attribution note states the results were obtained by an AI research collaboration in which an AI system occupied the principal research seat under human direction. Claude produced the search implementations, the independent reproduction of the load-bearing computation and the write-up; a tool-free GPT-5 produced the reduction to the lemma chain and the corrected hypotheses of several lemmas.
Verification
No independent review, though the load-bearing computation was reproduced by a second search with a different pruning strategy. Preprint, not refereed.
