Thanks for the answer. I meant with respect to x. So if R1 to R100 were all prime for example, for that range I consider it 100% dense by my definition. Inst

Thanks for the answer. I meant with respect to x. So if R1 to R100 were all prime for example, for that range I consider it 100% dense by my definition. Instead if 0.0000000…00000009% dense by computing: 100/R100. Hope that makes sense. My definition of course may be at odds with mathematical conventions.
