摘要

Utilizing high-performance computing, lookup tables, and the property of coalescence with respect to Collatz sequences, we present an approach to computing streaks of consecutive integers with the same Collatz height. Of particular interest is the extension of the OEIS (On-Line Encyclopedia of Integer Sequences) sequence A277109 through element 3950. At the time of publication, 9336 of the first 10000 elements of this sequence have been established. The current longest confirmed streak is for \(2^{3951}+1\) 2 3951 + 1 , with a streak of length \(2^{47}-1 \approx 10^{14.148}\) 2 47 - 1 10 14.148 .
