prime_parallelograms: Prime Parallelograms

In BastiHz/numberphile: Inspired by Numberphile Videos

Description

Usage

prime_parallelograms(n, plot = FALSE)

Arguments

n	The upper limit of the region that is searched for primes.
plot	Logical. Should the parallelograms be plotted?

Value

A data frame with columns for the primes, the result of the binary reversal and substraction, and the indices of the primes.
