The aim of this short note is to revisit some old results about groups of intermediate growth and groups of the lamplighter type and to show that the Lamplighter group \(L=\mathbb{Z}_2 \wr  \mathbb{Z}\)  is a condensation group and has a minimal presentation by generators and relators. The condensat...
