    • (See Evelyn Lamb's review of the paper on her Scientific American Roots of Unity blog: Mathematicians Predict What's in Your Wallet)

    • The files below contain data on the Markov chain for a "big spender's" wallet state in four currency scenarios considered in "What's in your wallet?". The set of wallet states and the transition matrix are available. The transition matrix is available in two formats: as a list of the nonzero entries and their positions (which can be passed to SparseArray) and in its full form as a list of lists. This data was computed using the Mathematica package PocketChange.

      pennyless purchaser:	213 states	sparse array rules	transition matrix
      quarter hoarder:	4125 states	sparse array rules (8 MB)	transition matrix (55 MB)
      U.S. currency:	6720 states	sparse array rules (15 MB)	transition matrix (144 MB)
      Shallit currency:	4238 states	sparse array rules (10 MB)	transition matrix (58 MB)
