The paper concerns some computer calculations done by Grayson in the fall of 1981 to compare the value of the regulator on ${K}_{2}$ of an elliptic curve with the value of the L-function at $s=2$. All curves on the Swinnerton-Dyer table [see “Modular functions of one Variable. IV” Proc. Internat. Summer School 1972, Univ. Antwerp, RUCA, Lect. Notes Math. 476 (1975; Zbl 0315.14014)] with Weil conductor $\le 180$, negative discriminant, and a rational torsion point of order $\ge 5$ were considered. These computations are explained by a modified form of a conjecture advanced by Bloch and Beilinson. They provide evidence for a lot of exotic relations between special values of Eisenstein-Kronecker- Lerch series and values of Hasse-Weil L-functions for elliptic curves without complex multiplication.
