Historical Note on Earthworm Sequence
The earthworm sequence was invented by, and appears in his $1991$ work.

His interest is specifically in whether each of the integers selected for $h_1$ ever returns to its starting point.

He fails to document the details of what happens for $h_0 = 50$.

The only reason this sequence appears here is because prime.mover found a piece of paper with his analysis on it in a big pile of material which is in the process of being recycled.
