- I play a game with triplets of digits (such as one finds on 99% of
- British numberplates), similar to the `four fours' game: combine them
- using some set of operators to generate the positive integers. You
- don't have to use all the digits, and the set of operators includes
- +,-,*,/ (exact division),! and can includes sqrt(), rem(), div(), or
- any others that strike my fancy.
-
- E.g. late-night driving Cambridge -> Newcastle, behind a truck with
- the plate DEG 652 B (say):
-
- 1 = 6-5
- 2 = 2
- 3 = 6/2
- 4 = 6-2
- 5 = 5
- 6 = 6
- 7 = 5+2
- 8 = 6+2
- 9 = 6+5-2
- 10 = 5*2
- 11 = 6+5
- 12 = 6*2
- 13 = 6+5+2
- 14 = hmm, nope
-
- So I overtake the truck and go on to the next vehicle.
-
- I've never done a search for the `best' triple, or even kept a record
- of scores: that would spoil the game.
