OEIS A228297: Need Help to Find Algorithm

[Gerald H]

Thomas, I installed your programme on a real 50g & have checksum A401 & size 560.5.

For input 100 the programme returned 81 in 334s.

While this is the best published programme so far (we don't know what the others have & not published), I would like the range of input on the real calculator to be at least in the millions.
