Definition:Leibniz Harmonic Triangle

Definition
The Leibniz Harmonic Triangle is a triangular array where:
 * the zeroth element in the $n$th row, counting from $0$, is $\dfrac 1 {n + 1}$
 * subsequent elements in the $n$th row are the zeroth element divided by the corresponding element of Pascal's triangle:


 * $\begin{array}{r|rrrrrr}

n & 0 & 1 & 2 & 3 & 4 & 5 \\ \hline 0 & \frac 1 1 \\ 1 & \frac 1 2 & \frac 1 2 \\ 2 & \frac 1 3 & \frac 1 6 &  \frac 1 3 \\ 3 & \frac 1 4 & \frac 1 {12} & \frac 1 {12} & \frac 1 4 \\ 4 & \frac 1 5 & \frac 1 {20} & \frac 1 {30} & \frac 1 {20} & \frac 1 5 \\ 5 & \frac 1 6 & \frac 1 {30} & \frac 1 {60} & \frac 1 {60} & \frac 1 {30} & \frac 1 6 \\ \end{array}$
