# All totally real cubic fields L with discriminant 800000 < d < 900000 and multiplicity m = 4

A single real quadratic field with four unramified cyclic cubic extensions
of principal factorization type Alpha 1 was found in this ninth range of length 100000.
We discovered and analyzed it on November 26, 2009, [2].

In this unexplored range, an eighth, ninth, and tenth unexpected and surprising result occurred (green color).
Three real quadratic fields with four unramified cyclic cubic extensions
of principal factorization type Delta 1 have been found.
The capitulation types turned out to be D.10: (4,2,2,3), resp. D.5: (1,1,4,4), resp. D.5: (4,2,2,4),
up to now only known for complex quadratic base fields.
(Discovered and analyzed [2] on November 29, 2009, resp. December 04, 2009, resp. December 06, 2009.)
