I suspect I am missing something very obvious, in which case could some kind soul put me straight?
I have the following code col := OrderedCollection new. (1 to: 9) permutationsDo: [ :each | col add: (each )]. I thought this would give me a collection containing all the permutations. However, what actually happens is that each of the arrays has been 'magically' sorted back into numerical order. If I change the code to read col := OrderedCollection new. (1 to: 9) permutationsDo: [ :each | col add: (each asOrderedCollection )]. Then the permutations are retained. Is this how it is supposed to work? Or, am I doing something wrong? Cheers Andy
