Errors that have been corrected
page 16: A calculation error led to the series of reciprocals of powers of 2, but the correct calculation actually leads to the series of reciprocals of the integers (divided by two). This series diverges. So with a deck containing an infinite number of cards, the top card can be shifted as far as you like. With a deck of 52 cards, the maximum possible overhang is about 2.27 times the length of a card. This means the edge of the top card can project more than two card lengths beyond the pile, thanks to the harmonic series construction.
