%F From _Chai Wah Wu_, Aug 04 2016: (Start)

%F a(n) = a(n-1) + a(n-28) - a(n-29) for n > 29.

%F G.f.: Sum_{k = 1..29} x^k /(1 - x - x^28 + x^29). (End)

%t With[{nn=100},Complement[Range[nn],Range[29,nn,29]]] (* _Harvey P. Dale_, Mar 11 2013 *)

%o (Sage) [i for i in range(0,100) if gcd(29, i) == 1]
