Sequence fans,

I wrote a program to find the number of squares whose vertices have
integer coordinates
less than or equal to n in absolute value, with one vertex in each
quadrant. (In particular,
there are no vertices on the coordinate axes.) It appears that the
number is A014820(n-1).
Is this correct?
