Prime Numbers and How to Avoid Them
... we can find infinitely many such numbers. The smallest is k= 201 44650 31451 65117 This is a “Sierpinski number”, which makes every term in the infinite sequence composite. Half are divisible by 3, a quarter divisible by 5, etc. ...

But some of the best mathematicians in world history have grappled with an almost equally simple question, which is “can you think of a higher prime number than I can ?” A prime number is any number gre ...
