Quadruplets of Totally Real Cubic Number Fields

Section 8. All totally real cubic fields L with discriminant 700000 < d < 800000 and multiplicity m = 4

Breaking through beyond Ennola and Turunen's domain [1]

In this unexplored range, a totally unexpected and surprising result occurred (green color).
A real quadratic field K with capitulation type b.10: (0,0,4,3) has been found.
710652 is the smallest discriminant, where
the group G=Gal(K2|K) is of lower than second maximal class.
(Discovered and analyzed [2] on November 09, 2009, independently from [1].)

Further, in this range, d=790085 is the smallest discriminant where
type a.2 appears in its first excited state with group G=Gal(K2|K) in CF2a(6).
(Discovered and analyzed [2] on November 25, 2009, independently from [1].)
