%N A112080 a(n) = difference between Jacobi-first-non-one(24n+1) and Jacobi-first-non-one(24n-1).
%C A112080 The definition of Jacobi-first-non-one is given in A112056.

%F A112080 a(n) = 4*A112054(n)+1.
%Y A112080 A112081(n) = a(n)/2. A112082 gives the points where a(n) is zero. A112059 
               gives the nonzero terms.
