The table on the mock-up banknote shows a fragment of a Turing Machine, taken from his paper introducing TMs (https://www.cs.virginia.edu/~robins/Turing_Paper_1936.pdf#pa...). Unfortunately, the chosen fragment is just used by Turing to establish notation and is otherwise meaningless. I hope in the final version they use better formulas, for example from the construction of the universal machine.
