Thanks to everyone who entered the previous David X Cohen puzzle competition – there was such a great response that here is another one.

Once again, this cryptarithmetic puzzle substitutes each letter for a number in order to make the multiplication below valid. This puzzle is based on the name of the great David X. Cohen (a writer on *The Simpsons* and co-creator of *Futurama*), such that his middle initial represents a multiplication sign. The nine different letters in DAVID COHEN represent nine of the digits 0 to 9 (which means it is trickier than the previous puzzle, as it was restricted to the digits 1 to 9).

**DAVID x COHEN = 250266547
