Are there any 0's in this sequence? I have computed that the first 1000 terms are all positive, the largest of these being a(980) = 1328602.
EXAMPLE
a(4) = 13 because A057033(13) = 4.
PROG
(MATLAB) function n = back_cyclic(n) i = 1; while i < n i = i + 1; if mod(n, i) == 0 n = n + i - 1; else n = n - 1; end end
