On the Narrow $2$-Class Field Tower of Some Real Quadratic Number Fields, Part II: Lengths
We determine precisely when the length of the narrow 2-class field tower is $2$ for most of those real quadratic number fields whose discriminant is not a sum of two squares and for which their 2-class groups are elementary of order $4$.
