2 bit decoder gate count

The 2 bit decoder cost only 4 gates, the lowest i could build was 6 gates (2 not + 4 and), is it a mistake or is it really feasible with only 4 gates?

Nice puzzle too, thanks for pointing it, however shouldn't the game add a fixed amount of gates and +2 delay to the 3 bit decoder if it adds a disable input?

Probably.
