%N A095779 Values of n for which A095777(n) is 10 (those terms which are expressible in decimal digits for bases 2 through 11, but not for base 12).
%e A095779 a(5)=35 because 35 when expressed in successive bases starting at 2 will produce its first non-decimal digit at base 12. Like so: 100011, 1022, 203, 120, 55, 50, 43, 38, 35, 32. In base 12, 35 is 2B.
