%N Absolute value of difference between counts of uninterrupted runs of 2 primes in A092639 and A092640.

%F Take the absolute value of the difference between counts of runs of 2 primes congruent to 1 mod 4 and 3 mod 4.

%e a(2)=3 because in A092639 the count is 2 and in A092640 the count is 5. 5 - 3 = 2.

%Y Cf. A092639, A092640.
