(Missing) Letters & Numbers

27 June, 2013

Love this nifty puzzle from Graham Hanlon, a maths teacher with a dangerous flair for wordplay. I wish I could say I’ve nailed the solution, though I’ve yet to examine the patterns in closer detail. Before I do, I thought I’d share Graham’s devilry in the meantime.

Beware all browsers, if you wish to figure out the code on you lonesome, then I suggest you resist the Comments, as all comers are welcome to identify the group. (And can you construct your own encoded list?)

In Graham’s own words: “I’m thinking of a set of 9 objects, where each 1 stands for the same letter and similarly for 2 and 3.” Meanwhile zero stands for any other letter. What’s the set?

1 2 3
0 0 0 0 2 0 0
0 0 3 2 1
0 0 0 0 0
0 0 0 1
0 2 0 0 0 0 0
1 0 0 2 0 3
0 0 0 3 2 1
3 0 0 0 2 3 0

Thanks to GH for the puzzle. A deft roll-call. And if you have a puzzle to share, send it in. These teasers are the mental callisthenics we love here.
