%N Triangle read by rows in which the n-th row contains the least set of n successive primes whose successive difference forms an arithmetic progression with common difference 2, (successive even numbers).
%C The difference between the first two primes in each row does not have to be two; what is required is that the second differences between the primes in each row are all twos. - _Harvey P. Dale_, Aug 09 2020
