Short Sleep, Mortality and Illness,We refine the Paige-Wexler canonical form for incidence matrices of finite projective planes and thus obtain a simple relationship between the incidence matrix and a corresponding planar ternary ring. We also demonstrate a simple relationship between an incidence matrix and a corresponding set of mutually orthogonal latin squares.

Short Sleep, Mortality and Illness,The relative merits of teams involved in a competition can be expressed by a partial ordering on the teams. The result of a round of the competition can be expressed by a multiplication of partial orderings, satisfying certain axioms. Several possible multiplications are described, and some properties of these multiplications displayed.

https://doi.org/10.1007/978-3-319-30572-1Deciding whether a triple system with . can be decomposed, or partitioned, into triple systems with smaller λ is NP-complete; this contrasts with the polynomial time algorithm for decomposing triple systems with .. Two extensions of this result are examined here — to triple systems without repeated blocks, and to triple systems with ..
