%N A070937 Number of times maximal coefficient (A025591) appears in Prod_{k<=n} 
               x^k+1, i.e. number of times highest value appears in n-th row of 
               A053632 or n-th column of A070937.
%F A070937 If n mod 4 = 0 or 3 then a(n) odd, otherwise a(n) even. For n>9: a(n)=A014695(n).
%e A070937 a(4)=5 since Prod_{k<=4} x^k+1 = 1+x+x^2+2x^3+2x^4+2x^5+2x^6+2x^7+x^8+x^9+x^10 
               and 2 appears as a coefficient 5 times.
