Euclidean fields having a large Lenstra constant
Armin Leutbecher · Annales de l’institut Fourier · 1985
Based on a method of H. W. Lenstra Jr. in this note 143 new Euclidean number fields are given of degree n = 7 , 8 , 9 and 10 and of unit rank ≤ 5 . The search for these examples also revealed several other fields of small discriminant compared with the lower bounds of Odlyzko.
