... Thus there are six non-isomorphic abelian groups of order 504. Here is an interesting consequence of the fundamental theorem: Corollary 1.11. If m divides the order of a finite abelian group G then there is a subgroup H of G of order m. Proof. By (1.9) G is isomorphic to Zpa1 1 × Zpa2 2 × · · · × Zp ...

... q/(q − 1) − O(q −n/2 ) found by Guibas and Odlyzko. Our bound is not sharp, and in fact Csirik gives the first player’s optimal strategy for q = 2 [1]. He finds that in a well-played game the second player’s best odds are (2n−1 + 1)/(2n−2 + 1), a figure whose deviation from 2 tends to 2/3 of that of ...

... of f then one says that f is lead-reducibleby g. If c is the coefficient of m in f and m = q lm(g), the one-step reduction of f by g is the operation that associates to f the polynomial The main properties of this operation are that the resulting polynomial does not contain the monomial m and that t ...
