The existence of non-trivial hyperfactorizations ofK 2n

Combinatorica, 1991
The paper concerns nontrivial hyperfactorizations of the complete graph \(K_{2n}\). A \(\lambda\)-hyperfactorization of \(K_{2n}\) is a collection of linear factors of \(K_{2n}\) such that each pair of non-adjacent edges appears exactly in \(\lambda\) factors. In general, some factors may appear more than once.

Cyclic Perfect One Factorizations of K2n

1987
Abstract Recently Hartman and Rosa characterized those n for which K 2n admits a cyclic one factorization. We show that K 2n admits a cyclic perfect one factorization if and only if n is prime. We also show that if n is prime there is a one to one, onto correspondence between cyclic perfect one factorizations on K 2n and starter induced ...

On Certain Families of Disjoint Perfect Matchings in K2n

1983
How can one obtain 2 n – 1 disjoint perfect matchings in the complete graph K 2n by “turning” a given perfect matching round a fixed vertex? How many ways are there to do it? Such problems lead us to investigate, for /2 n – 1, some properties of functions obtained by taking the odd part (in the functional sense) of permutations.

Functionalised phosphines: Structure of bis(2-aminophenyldiphenylphosphine-K2N, P)copper(I) perchlorate ethanol solvate

Inorganica Chimica Acta, 1994
Abstract The functionalised phosphine, 2-aminophenyldiphenylphos- phine (2-PNH 2 ) reacts with [Cu(CH 3 CN), 4 ]CIO 4 , to yield the complex [Cu(2-PNH 2 ) 2 ]CIO 4 ·C 2 H 5 OH. The compound has been characterised spectroscopically and the structure determined by the X-ray method. The crystals are monoclinic with a  12.816(4), b  27.547(8), c 
