Puzzles and Curious Problems by Henry Ernest Dudeney: $309$
- Domino Sequences
- A boy who had a complete set of dominoes, up to double $9$, was trying to arrange them all in sequence, in the usual way --
- $6$ against $6$, $3$ against $3$, blank against blank, and so on.
- His father said to him, "You are attempting an impossibility, but if you let me pick out $4$ dominoes it can them be done.
- And those I take shall contain the smallest total number of pips possible in the circumstances.
- Now, which dominoes might the father have selected?
- Remember that the dominoes in common use stop at double $6$, but we are here using a set up to double $9$.
