an out-of-print book titled The Valenzetti Equation about an equation derived by an also-fictional mathematician of that name. Amazon's "exclusive note" on their Bad Twin page mentions that The Valenzetti Equation is Troup's first book. The "Lost Experience" has revealed that the objective of the DHARMA Initiative is to alter any of the six factors of the Valenzetti Equation, revealed to have a huge impact on the date the human race will destroy itself, whether by global warming, chemical warfare, overpopulation or many other possible means. These factors are each associated with a number in the Valenzetti Equation, which are the numbers frequently mentioned in the show: 4, 8, 15, 16, 23 and 42.
