A055832 is defined as "A sequence of 2n primes with symmetrical gaps about
the center starts at this prime.", yet the first term is 3, relating to gaps
5 - 3 = 2 and 7 - 5 = 2, so there is no "center" .  Shouldn't the first term
of A055832 be 5?

If it was then A175309(2n+1) would = A055832(n) for all n>=1.

Best regards,
