%N A196673 Chebyshev primes that begin a record gap to the next Chebyshev prime.
%C A196673 The Chebyshev primes (of index 1) are such odd primes that satisfy li[psi(p)]-li[psi(p-1)]<1 (sequence A196667), where li(x) is the logarithmic integral and psi(x) is the Chebyshev's psi function.
%C A196673 The present sequence lists the Chebyshev primes that begin a record gap to the next Chebyshev prime.
