Composite “LAST DIGIT Patterns”

These Patterns are composed from various combinations of Last Digits 1 3 5 7 and 9. What do we see? Anything surprising? Amazing? Can we tell Primes from Non-Primes? Enjoy!

What more do we want to see? What could be presented better? Who comes up with Colour Themes for “Digital Number Formats”? Microsoft? For royalties? My Copyright protection depends on NFTs!
