The Riemann R function is as follows:
$$R (x)=\sum _{n=1}^{\infty } \frac{\mu (n) \text{li}\left(x^{1/n}\right)}{n}.$$
This uses the Möbius function as well as the logarithmic integral.
From the wikipedia, the Möbius function is defined so that for any positive integer \$n\$, \$μ(n)\$ is the sum...
