Definition
The Stolarsky-Harborth constant is the lower bound for the number $\beta$ defined as:
- $\beta > \dfrac {P_n} {n^{\lg 3} }$
where:
- $P_n$ is the number of odd elements in the first $n$ rows of Pascal's triangle
- $\lg 3$ denotes the logarithm base $2$ of $3$.
Its value is given by:
- $\beta \approx 0 \cdotp 81255 \, 65590 \, 160063 \, 8769 \ldots$
This sequence is A077464 in the On-Line Encyclopedia of Integer Sequences (N. J. A. Sloane (Ed.), 2008).
