Consider Sequence A185028 of the
Online Encyclopedia of Integer Sequences.
Can you answer the question that appears in the "COMMENTS"? Specifically, can you prove or disprove the finiteness of the sequence? The sequence and the question were both formulated by Moshe Wolf. It got to me in riddle form by Oded Margalit. Thanks, Oded and Moshe! |
