My main difficulty in code would be connecting them up correctly. Minimal possible length for it to go to is 256.

I cannot imagine that there is a 256-letter-string containing 252 different anagrams, if in the exemple 13 are needed instead of 12 (I suppose that 13 is the best solution).
The best 270-letter-string I have found until now contains 249 different anagrams.

Same procedure as last month - only 17 solvers until now. I have found some 270-letter-strings containing 251 different anagrams, but I continue to seek...
