Abstract
Mennicke–Newman lemma for unimodular rows was used by W. van der Kallen to give a group structure on the orbit set \(\frac{Um_{n}(R)}{E_{n}(R)}\) for a commutative noetherian ring of dimension \(d\le 2n-4.\) In this paper, we generalise the Mennicke–Newman lemma for \(m\times n \) right invertible matrices
