For instance, all primes p 19 have h p = 1, so they are regular. Since h 23 = 3, 23 is regular. All primes less then 100 are regular except for 37, 59, and 67: h 37 = 37, h 59 = 359233, and h 67 = 6712739. It is ...

Lemma 7.1: Every element in A which is prime to 1 + ζ has norm equivalent with 1 mod 32. Proof: ( I do understand this proof, so I will omit). So if we can find q, r sush that 1 + ( 1 + ζ) 5 = q ( 1 + 6) 6 + r with N L / Q ( r) < 64, Lemma 7.1 and Proposition A.5 (6) and (9) tell us that r is either a unit or a ... tryon christmas lights 2021

Introduction For a positive integer n, an nth root of unity in a eld is a solution to zn = 1, or equivalently is a root of Tn 1. There are at most ndi erent nth roots of unity in a eld since Tn 1 has at most nroots in a eld. A root of unity is an nth root of unity for some n.
