Let K be an abelian group of order v. A Steiner quadruple system of order v(SQS(v)) ( K, B) is called symmetric K-invariant if for each B is an elemen......

In 2008 Branden proved a (p, q)-analogue of the gamma-expansion formula for Eulerian polynomials and conjectured the divisibility of the gamma-coeffic......
