%N Primes p such that p+1 is in A276573, the infinite trunk of least squares beanstalk.
%C These seem to be substantially more common than A277888, even though odd terms are slightly more common in A276573 than the even terms. See also comments in A277487.

%F a(n) = A278486(n) - 1 = A276573(A278485(n)) - 1.
%o (Scheme) (define (A278487 n) (+ -1 (A276573 (A278485 n))))
%Y One less than A278486.
%Y No common terms with A277888, some common terms with A278494.
%Y Cf. A277486 (gives the count of these primes in each range [n^2, (n+1)^2]).
