Consider, for d an integer, the set S(d) of prime numbers p such that: there exists a number field K of degree d, an elliptic curve E overK, and a point P in E(K) of order p. It is a well-known theorem of Mazur, Kamienny, Abramovich and Merel that S(d) is finite for every d; moreover S(1) and S(2) are known. In [7], we tried to answer a question of Kamienny and Mazur by determining S(3), and we...
If a Steiner system S(4, 5, 17) exists, it would contain derived S(3, 4, 16) designs. By relying on a recent classification of the S(3, 4, 16), an exhaustive computer search for S(4, 5, 17) is carried out. The search shows that no S(4, 5, 17) exists, thereby ruling out the existence of Steiner systems S(t, t+ 1, t+ 13) for t ≥ 4.

The function that assigns to each matrix game (i.e., the mixed extension of a finite zero-sum two-player game) its value is axiomatized by a number of intuitive properties.
Klein of the Wharton School's Econometric Forecasting Associates expect GNP to increase about 7 per cent a year in current dollars, while the price level creeps up at only a noninflating 2.5 to 3 per cent a year. The unemployment rate, now close to the 6 per cent mark, should drop to 4.5 per cent by 1973 and stay close to that for the rest of the decade. "In human terms, this holds the promise ...
