| Abstract [eng] |
In this note we consider the sequence of rational numbers (Formula presented). We show that the power of 2 in the expansion of bn is unusually large, at least n+1−log2(n+1), and that this bound is best possible. The sequence bn, n = 1, 2, 3, …, is related to the sequence A0031449 in the On-Line Encyclopedia of Integer Sequences. |
