I just noticed that

%S A068829
%T A068829 191,197,211,223,227,239,251,257,263,269,277,281,307,311,331,347
%N A068829 Geometrically strong primes: primes which are larger than the
geometric mean of
           their neighbors.

is an erroneous version (it lacks a(2)=11) of

%S A046869 5,11,17,29,37,41,53,59,67,71,79,97,101,107,127,137,149,157,163,173,

%N A046869 Good primes (version 1): p(n)^2 > p(n-1)*p(n+1).
