Zassenhaus lemma [also: lemma of Zassenhaus]

Lemma {n} von Zassenhausmath.

• The Zassenhaus lemma gives an isomorphism between certain combinations of quotients and products in the lattice of subgroups.
• The Zassenhaus lemma (also known as the butterfly lemma) is sometimes called the fourth isomorphism theorem.
• In mathematics, the butterfly lemma or Zassenhaus lemma, named after Hans Zassenhaus, is a technical result on the lattice of subgroups of a group or the lattice of submodules of a module, or more generally for any modular lattice.
• It is often proved using the Zassenhaus lemma. [...] gives a short proof by intersecting the terms in one subnormal series with those in the other series.
