Abstract
It is proven that if a finite group has a normal subgroup with -index (where is a prime) and is solvable, then for a -subgroup of , if the Scott -module with vertex is Brauer indecomposable, then so is the Scott -module with vertex , where is a field of characteristic . This has several applications.
