    Notes: Abstract We describe an implementation of a general standard basis algorithm, valid for any monomial ordering compatible with the natural semigroup structure. We concentrate on new strategies which have proved useful, in particular in the non-wellordering case. Moreover, we describe the first implementation of Schreyer's method to compute syzygies and compare it with other, more classical methods. Comparisons of the computing time of several examples in the system SINGULAR give hints as to which strategies should be used in different classes of examples.

    Description / Table of Contents: Li1.25ZnGe and LiCu0.93As - Two Isotypic PhasesThe structures of the isoelectronic and isotypic phases Li1.25ZnGe and LiCu0.93As have been determined by single-crystal investigation. With 3 formula units in the cell the structure of the compounds can be described as a 3-layer lattice. The isomorphism of them is similar to that observed in the phases Li2ZnSi and Li2CuP.
    Notes: Die Strukturen der isoelektronischen Phasen Li1,25ZnGe und LiCu0,93As wurden durch Einkristalldaten ermittelt. Sie sind isotyp und bilden bei 3 Formeleinheiten in der Elementarzelle ein trigonales Dreischichtengitter. Damit liegt eine ähnliche Isotypie vor wie bei den bereits bekannten isoelektronischen Phasen Li2ZnSi und Li2CuP.
