presidents with non-consecutive terms

[A Random Person]

Which presidents can you see not having consecutive terms in office.

The two who I can see likely are:

John Adams, he served six terms as a congressman after being voted out.

FDR, a mistake in office costs him one election, but is still able to win back the hearts of the americans.

Theodore Roosevelt could have done it. He came extremely close to doing it IRL.
