Look up prime number race instead. Indeed it is well known and well studied.

The other day I realised that all the twin primes, excluding, but indirectly including 5 and 7, can be turned into 3 tables of twin primes each headed by very basic calculations from the first three prime numbers, 2, 3 and 5. ( I was quite surprised by this, though I've always believed rightly or wrongly that the secrets of the primes must be discernable from the first few )

The three columns of prime pairs generated under 2, 3 and 5 obviously contains large numbers of non-prime pairs as well, giving biases in one column or another.

Have these biases also been well studied?

Kind regards

Bob
