Grover Cleveland was both the 22nd and 24th President, so a(22) and a(24) are the years in which he began each of his two non-consecutive terms.

Examples

			Thomas Jefferson, the third American President, served two full terms. His first term in office began in a(3) = 1801. His successor, James Madison, began his first term in office in a(4) = 1809.
a(46) = 2021 because Joseph R. Biden, Jr., the 46th President of the United States, assumed office in 2021.
