Let T(S,Q) be the sequence obtained by starting with S and repeatedly reversing the digits and adding Q to get the next term. This is T(10016,5). 100016 is the first S for which T(S,5) reaches a cycle of length 756. The cycle is simply the first 756 terms, which then repeat. A full period is given in the table.
