Problem #225

The sequence 1, 1, 1, 3, 5, 9, 17, 31, 57, 105, 193, 355, 653, 1201 ...
is defined by T_(1) = T_(2) = T_(3) = 1 and T_(n) = T_(n-1) + T_(n-2) + T_(n-3).

It can be shown that 27 does not divide any terms of this sequence.
In fact, 27 is the first odd number with this property.

Find the 124^(th) odd number that does not divide any terms of the above sequence.
