... primes. For example, the set of positive values taken on by the following bizarre polynomial of degree 25 in 26 variables is precisely the set of primes, where the variables a, b, c, . . . , z vary over the non-negative integers [4].

3. Prove that n3 + (n + 1)
... 3n + 6n = 3n(n2 + 2). We’ve reduced the problem to showing that 3n(n2 + 2) ≡ 0(mod9), or n(n2 + 2) ≡ 0(mod3). Again, this can be verified by checking for n = 0, 1, 2. This is better than Solution 1, but even better: Solution 2a: Notice that n2 + 2 cannot be factored in the integers, but (!) 2 ≡ −1(m ...

... at n=k. Thus one of the prime factors 6k1 has been found. Next we look at the quotient M/(6m1) for m=1,2,3,..,sqrt(M)/ 6. Since M is smaller than N the number of divisions required in this second case will be less. If we evaluate this new quotient, one typically finds a new prime 6m1 value for t ...
