A warehouse printer makes an 8-digit shipment label by joining six pre-printed strips end-to-end. Four strips have one digit on them: 0, 1, 2, 9. Two strips have two digits on them: 19 and 20. Each strip must be used exactly once, and the final label is invalid if its first digit is 0. How many valid labels can the printer produce?

Before them stood a short man with a neatly trimmed white beard, clad in the crimson-and-gold robes of a senior scholar of Mendevian Crusaders. H...
