Print it. Frame it. Marvel at it. This mathematical gem is yours forever!
What resolution are the images?
The PNG is high-resolution and the PDF is vector-based, so you can print it at any size—from a postcard to a poster—without losing quality.
How long does generation take?
Usually under ten minutes. Longer names take more time as the prime numbers get larger--we aim to have a result for you as soon as our computer cluster has identified your prime.
What characters can I use?
You can use letters A-Z, numbers 0-9, spaces, and hyphens. Try names like "MARY JANE" or "MARY-JANE" for compound names.
What are the three file formats for?
PNG is perfect for sharing online or on screens. PDF is ideal for printing at any size. TXT contains the raw prime number.
Why do you use 8s and 1s?
We chose these digits as they display with high contrast. The bold 8s form the visible letters while the light 1s fade into the background, creating a striking visual effect.
Does my purchase include a frame?
No, but we are working hard to offer a framing service soon--stay tuned!
Your number is verified using the Baillie-Pomerance-Selfridge-Wagstaff (BPSW) primality test. It combines a Miller-Rabin test for base-2 with a Lucas test. While technically a probable prime, no counterexample has been found in over 40 years of searching. Your prime is unique and almost certainly truly prime.
