Comments

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.

Comments

These terms currently add up to two more than the total number of Vice Presidents who have already completed their terms because (to date) two VPs were VPs for two different (consecutive) Presidents.

Examples

			a(3)=2 because Thomas Jefferson, the third President, had two Vice Presidents (a different one during each of his presidential terms of office). a(22)=1 because Grover Cleveland, the 22nd President, had one Vice President while he was the 22nd President. a(24)=1 because Grover Cleveland, the 24th President also, had one Vice President while he was the 24th President (this VP happened to be a different person).
