[#R649] The requested maximum is at least fourteen
claim. A length-14 rainbow divisor-count interval is certified, and exhaustive search proves 14 is the exact maximum through endpoint \(10^{10}\); whether a longer interval ends between \(10^{10}\) and \(10^{12}\) remains open.
1Summary
The interval \[ 1745175039\leq n\leq1745175052 \] has divisor-count vector \[ (12,80,16,96,8,6,32,4,24,128,2,48,20,36). \] All fourteen entries are different. Its final integer is below \(10^{12}\), so the candidate's maximum \(L\) satisfies \[ L\geq14. \] The companion sweep finds this as the first length-14 record. The global upper bound requested by the candidate remains open in this fixture because the exhaustive computation stops at \(10^{10}\).
Reproduced evidence. Recorded scope: the optimization over positive m and L satisfying m+L-1 <= 1000000000000.
2Evidence
