COMMENTS

The Chebyshev primes (of index 1) are such odd primes that satisfy li[psi(p)]li[psi(p1)]<1 (sequence A196667), where li(x) is the logarithmic integral and psi(x) is the Chebyshev's psi function.
The present sequence lists the nth Chebyshev primes that are equal to the 2nth primes.
See A196674 for the number n at the zeros of the function a(n)p_{2n}, where a(n) is the nth Chebyshev prime and p_{2n} the 2nth prime.
