It's 36.

I usually start with Reagan being #40. Counting back the presidents it reveals that Nixon was the 37th president, not the 36th. You're right, you can't have two Grover Clevelands on the same hall, so not including his 2nd non-consecutive term, the correct answer was one of the choices listed you've mentioned.
