By generalizing the construction of complete sets of mutually orthogonal latin squares from affine planes, showed how to obtain complete sets of mutually orthogonal frequency squares from affine geometries. In this paper, the construction of a complete set of frequency squares not equivalent to an

An inconclusive proof in a 1937 paper by G. Chogoshvili spawned an interesting dimensiontheoretic conjecture which we call the Chogoshvili-Pontrjagin Conjecture. In 1991, Y. Stemfeld found an ingenious counterexample to this conjecture which he and M. Levin greatly generalized in 1995. In this note
## Abstract The following conjecture of Brualdi and Shen is proven in this paper: let __n__ be partitioned into natural numbers no one of which is greater than (__n__β+β1)β/β2. Then, given any sequence of wins for the players of some tournament among n players, there is a partition of the players i
