%N Numbers n such that there exists a binomial coefficient C(n,k) where C(n,k)-1 and C(n,k)+1 are twin primes and 2<=k<=floor(n/2).
%C The integer 202 occurs twice because both C(202,34) and C(202,69) yield twin prime pairs.
%H <a href="http://science.kennesaw.edu/~jdemaio/twinbc.htm">Source</a>
%e The integer 11 is a member of the sequence because C(11,5)=462 and 461 and 463 are twin primes.
%Y A051735, A051771.
