[#R66] The literature audit found asymptotic and central-coefficient results

View evidenceOpen source ↗

1Summary

The sources located do not give the two-parameter bounded record at one million.

OEIS A048784 tabulates \(\tau\binom{2m}{m}\) for central binomial coefficients and cites Fedorov's asymptotic formula for that sequence. Fedorov's separate Mathematical Notes paper studies upper and lower orders of ratios between divisor counts of adjacent binomial coefficients. Erdős and Kolesnik study prime-power divisibility near the middle. These sources concern central values, asymptotics, or individual prime powers.

Searches by the exact objective, divisor-record terminology, and the pair of bounds \(k<n\leq10^6\) found no published table or complete two-parameter sweep. The exact value at the requested cutoff therefore remains unresolved in this record. The prefix theorem and cutoff-scale lower bound above are the certified results supplied here.

Inconclusive evidence. Recorded scope: published and public-sequence work on divisor counts and prime exponents of binomial coefficients.
