The sequence cycles at a(21)=36 and the loop has 104 terms. It is the same loop as in A112437 "Next term is the sum of the last 10 digits in the sequence, beginning with a(10) = 6" and the first term of this 2-loop is the 59th term of that 6-loop . Computed by Gilles Sadowski. %e A112434 a(21)=36 because 2+4 + 2+7 + 2+7 + 3+3 + 3+3 = 36 %Y A112434 Cf.
