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).
