Chemical isomerism, a challenge for algebraic combinatorics and for computer science,ular structure elucidation, where a molecule has to be identified from experimental, usually from spectroscopic data. MOLGEN provides the full wealth of mathematically possible structures (multigraphs with given degree sequence, where the vertices are colored by atom names), from which further chemi

Algorithmic/Architectural Level Refinement,s equivalent to a certain double coset problem, no polynomial algorithm can be expected to work in the general case. But the reduction techniques used still allow to solve problems of an interesting size. As an example we explain how the 7-designs in the title were found. The two simple 7-designs wi

Analog Circuits and Signal Processingd by the algebraic-combinatoric “Bézout number” of the system which is given by the Hilbert function of a suitable homogeneous ideal. However, in many important cases, the value of the geometric degree is much smaller than the Bézout number since it does not take into account multiplicities or degre
