%N Start of the first string of exactly n consecutive pairs of cousin primes.

%H Eric Weisstein's World of Mathematics, <a href="https://mathworld.wolfram.com/CousinPrimes.html">Cousin Primes</a>

%e a(5) = 853 as the consecutive primes 853, 857, 859, 863, 877, 881, 883, 887, 907 and 911 form exactly five consecutive pairs (p, p+4) of cousin primes and no smaller string of consecutive primes has this property.

%Y Cf. A087641 (similar for twin primes), A095969, A095970, A095971.
