... • Each such number is n2|G| (“small”). • So there are |G| (“few”) such numbers. • This gives a, b, c, d with (a,b) (c,d) and na * pb = nc * pd • Therefore, n = pe which implies n = p. t = Or(n,p) I: set of introspective numbers I: set of introspective numbers Q: set of introspective polynomia ...

... (With the convention that a product could be of just one prime!) Proof p.278, is by strong induction Theorem (Euclid) If p|ab then either p|a or p|b. Proof p.279. The proof makes use of an earlier result that if n|ab and gcd (n, a) = 1 then n|b. Example 12|4 × 6 yet 12 - 4 and 12 - 6. This proves th ...

... is prime, then p = u2 + v 2 , and (2) if p ≡ 3 (mod 4) is prime, then p = u2 + v 2 is impossible. Forgetting that we have already proved (2) [[u2 , v 2 ≡ 0 or 1 (mod 4) , so the sum can’t be ≡ 3]], it turns out that what is really relevant to the discussion is under what circumstances the equation x ...
