My guess is that a row is not allowed if it is a 'shifted' version of any previous row. There must be an existing name for such things. UPDATE: The name that I wanted is Cyclic-Permutation (The 'restricted definition'). Bill	[reply]

G'day hippo, I'm seeing this pattern: In the first (acceptable) result, all elements have a different order and no elements have been previously used. In the second (unacceptable) result: the first element has the same order; the third element has been previously used. I put this here to keep all the guesswork together. It was an afterthought; see code written earlier. — Ken	[reply]

My guess: No values repeated in a column. But let's wait for a reply. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

My guess: No values repeated in a column. That was my first guess too, but the 4's are repeated in the third column of the first example.	[reply]

Oops, are they? I might need stronger glasses, then :-( `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

I must admit that I am struggling to deduce the criteria for which is an allowed shuffle and which is not. I did sit puzzled for a short while wondering if I was missing something obvious. It's a relief to learn I am not the only one struggling to comprehend the criteria!	[reply]
