Just to clarify, the numbers that {1,2,3,4,5,6} map to do not have to be prime numbers for Egan's solution to work, they only have to all be co-prime with each other (you get both if you look for only prime numbers).

To that end \(6x+1\) makes for an even shorter program. ( by checking 8645, 38285, and 108965). (maps to 7,13,19,5^2,31,37).
