If n=A000695(k_n)+2*A000695(l_n), then a(n) is the number of nonnegative integers m<n such that k_m differs from k_n and l_m differs from l_n.
Let us call integers m and n collinear one to another if either A059905(m)=A059905(n) or A059906(m)=A059906(n). Then a(n) is the number of noncollinear to n nonnegative integers not exceeding n.
