## Counting the primes

One of the key missing elements of the prime number sequence is the ability to identify the i th  term in the sequence. That works two ways – can we calculate the  i th  term and if we have a prime number … Continue reading

## Secondary arrays

This element needs to be read after that titled “Composite arrays“. A secondary array of integers (a mix of primes and composites) emerges by dividing the associated composite array by Pn  i.e. by the prime number “associated” with that composite … Continue reading

## Counting the prime pairs

Is there an infinite number of prime pairs? How frequent are prime pairs? Why are their prime pairs? Intriguing questions best examined from the composites: why do they exist for starters? Look at the role of prime factors 2 and … Continue reading
