摘要: Abstract One hard step in the computation of Galois groups by Stauduhar’s method is construction relative invariants. In this note, a representation-theoretic approach given for case an intransitive group. second part article, it shown that can be used have suitable subgroup. The solves open question Fieker and Kluners.
