részfaktoriális
Részfaktoriális, also known as partial factorial, is a term used in combinatorial mathematics. It refers to a specific subset of all possible factorial arrangements of a set of items. In standard factorial calculations, n! represents the total number of ways to arrange n distinct items in a sequence. Részfaktoriális, however, considers only a selection of these arrangements based on certain criteria or constraints.
The concept is often employed in experimental design, particularly in fractional factorial designs. These designs are
The selection of which combinations to include in a részfaktoriális is not arbitrary. It follows specific aliasing
