Why is this free?

We are using these files to test our user-interface, URL translation, download relay, load management, traffic analysis, network, database, and calculation systems. We are professionally interested in the progress of education in mathematics and engineering.

Comparable resources

The Nth Prime Page can be used to verify any small random sample of primes listed within our databases.

Independently calculated ℙ<10¹⁰ are available at Mr. T. Everett's Web site in a delimited text based format (change the filename extensions to ".7z" before opening with 7-Zip!)

A basic prime factorisation algorithm is also available on this Web site.
