👉 In mathematics, a preindependence is a property of an element in a group that allows it to be expressed as a product of elements from the same subgroup. This means that if we have two elements \(a\) and \(b\) in a group, where \(a\) is not equal to \(b\), then there exists another element \(c\) such that \(ac = ba\) and \(bc = ab\). The preindependence property ensures that when \(a\) and \(b
