An inequality using any of the inequality symbols has an infinite number of solutions. An inequality using
all but one of the inequality symbols also has an infinite number of nonsolutions. Which inequality
symbol produces an inequality with a finite number of nonsolutions?

The "not equal" sign, ≠.

Reason: any inequality with ≠ (e.g. x ≠ a) has infinitely many solutions (all reals except a) but only the single nonsolution x = a (finite). Any inequality with <, >, ≤, or ≥ has its nonsolutions containing a half-line or interval (e.g. for x < a the nonsolutions are x ≥ a), hence infinitely many.
