 These give exactly three distinct sizes for every interval class. Hence S is SV3.
-In this case S has two chains of Qs, one with floor(n/2) notes and and one with ceil(n/2) notes. Every instance of Q must be a k-step, since Q = αa + βb + γc is the only way to write Q in the basis (a, b, c). Thus S also satisfies the generator-offset property with generator Q.

Every instance of Q must be a k-step, since Q = αa + βb + γc is the only way to write Q in the basis (a, b, c); so S is well-formed with respect to Q. Thus S also satisfies the generator-offset property with generator Q.
