A144478 Period 9: repeat 1,0,5,7,6,2,4,3,8. 1

%I #18 Dec 12 2023 08:21:10

%S 1,0,5,7,6,2,4,3,8,1,0,5,7,6,2,4,3,8,1,0,5,7,6,2,4,3,8,1,0,5,7,6,2,4,

%T 3,8,1,0,5,7,6,2,4,3,8,1,0,5,7,6,2,4,3,8

%N Period 9: repeat 1,0,5,7,6,2,4,3,8.

%C Essentially the same as A145577.

%H <a href="/index/Rec">Index entries for linear recurrences with constant coefficients</a>, signature (0,0,0,0,0,0,0,0,1).

%F a(n) = A144390(n) mod 9.

%F a(9n+2)+a(9n+3)+a(9n+4) = a(9n+5)+a(9n+6)+a(9n+7) = a(9n+8)+a(9n+9)+a(9n+10) = 12.

%F a(n+4)-a(n+1) = period length 9 (repeat 6,-3,-3,-3,6,-3,-3,-3,6).

%o (PARI) a(n)=[1,0,5,7,6,2,4,3,8][n%9+1] \\ _Charles R Greathouse IV_, Jun 02 2011
