2^n-1 seed will always pass through (5) on its

return too 4,2,1,4,2,1...

The only exception being 2^65 -1

Checked through the first 100 odd (n) seeds

where the last odd tested was 2^201 -1

and the only one that does not pass through (5)

is 2^65-1.

Where (n) is odd and > 201, are there

other 2^n -1 seeds that do not pass

through (5) like 2^65-1?
