%N Numbers n such that (1,n) is "good".
%C Let S be the set of nonnegative integers whose base 4 representation does not contain the digits 2 or 3. A pair (M,N) of nonnegative integers is called "good" if every nonnegative integer can be represented uniquely in the form M*s_1 - N*s_2 where s_1 and s_2 are in S.
