Have you ever needed to do some hardcore prime numbers work?

To teach your kids the multiplication tables of the elite?

The Amazing Prime Table Multiplication Matrix Thing

Usage

Dependencies

lein

Displaying the 10 x 10 prime multiplication table from the terminal

lein run

Displaying a n x n table rom the repl

(primes-multiplication-table n)

Generating a collection of the first n primes

(primes n)

Using prime-table as a library

Just add [prime-table "0.1.0-SNAPSHOT"] as a dependency, require prime-table.core, and enjoy

Considerations

Populating the matrix is speedy (3.8s for a 1000 x 1000 matrix in a quick test) so the first limitation for scalability is in the printing.

prime-table uses tabs for printing the table, so if you print a table with 447 primes or more, you should use other method for printing than print-matrix because the tabs will jump.

In practice, tables of 25 or less primes will probably not be distorted.
