 OFFSET 0,3 COMMENTS The repeating part contains all ten digits. LINKS Index entries for linear recurrences with constant coefficients, signature (0,0,0,0,0,0,0,0,0,1). FORMULA a(n) = A171507(n+1) mod 10. a(2n) = A059629(n) mod 10; a(2n+1) = A139788(n). abs(a(n+1)-a(n)) = A010686(n). a(n) = (1/5)*(3*(n mod 10) + 3*((n+2) mod 10) - 2*((n+4) mod 10) + 3*((n+6) mod 10) - 2*((n+8) mod 10)), with n >= 0. - Paolo P.
