摘要翻译:
本文研究了除数类群中具有非循环扭转的Fano三重方程组。由于它们都可以作为三重Fano的商得到,因此我们也得到了所有可以作为加权射影空间中低余维Fanos的商得到的例子。

英文摘要:
In this note we study Fano threefolds with noncyclic torsion in the divisor class group. Since they can all be obtained as quotients of Fano threefolds, we get also all examples that can be obtained as quotients of low codimension Fanos in the weighted projective space.
