The real quadratic base field K with discriminant d = 710652

710652 is the smallest discriminant of a real quadratic field K
with capitulation type b.10 (0,0,4,3),
symbolic order V4,4, and group G=Gal(K2|K) in CBF1b(6,8)
of lower than second maximal class (e = 4).

710652 is also the smallest discriminant of a real quadratic field K for which 2 of the 4 unramified cyclic cubic extensions Ni|K
have non-galois absolute cubic subfields Li|Q with 3-class number 9.

We give the complete data needed to determine the capitulation type and the group G=Gal(K2|K).
