For example, 192 is one of them because 192, 384, 576 contain 1 to 9 each once. 273 is another one of them because 273, 546, 819 contain 1 to 9 each once.

Billy-Bob walks into a bar and says, "Bartender, one round for everyone, on me!"
The bartender says, "Well, seems you're in a really good mood tonight, hm?"
Billy-Bob says, "Oh, you can bet on it! I just got hired by the city to go around and remove all the money from parking meters. I start on Monday!" The bartender congratulates him and proceeds to pour the round.
Monday evening arrives. Billy-Bob comes back into the bar and says, "Bartender, two rounds for everyone, on me!"
The bartender says, "Well now! If you're so happy just over having this new job, I can just imagine how happy you'll be when you get your paycheck!"
Billy-Bob looks at the bartender with a wondrous look on his face, pulls out a handful of quarters from his pocket, and says, "You mean they'll PAY me too?"
