A single digit different from zero is written on each of three cards (the digits on different cards are not necessarily different). We know that any three-digit number formed from these cards is divisible by six. Moreover, a three-digit number divisible by eleven can be formed from these cards.
What digits can be on the cards? Determine all possibilities.
