comment Expressing a sequence with two sigma notation
$\NN$ does have zero. You don't need to add it.

@0ana : 13524 and 14253 are not related by a rotation but by a reversal.

Is this something you came up by yourself ? If not, please give the source by respect of the authors.

@TylerHG : these are not zeroes but misinterpretations of underflows.

comment What does a non-mathematician need to google to learn more about latin squares in which each number in each row always has a different successor?
@hcc23 : I am also interested by your opinion on my sequential solution to your experimental problem.

No you don't miss anything. You spotted a mistake in my terminology. I should have said cyclic (I will edit it), because in the Williams construction described on the H. Bruin page, this is the same array of differences from one column to the next. In fact, this property might be considered a disadvantage if there is an interaction between the properties of your operations and this sequence of difference, making this series of experimental tests not "mixed" or "unbiased" enough.

Added another point of view for the original application of the result.

Dear @hcc23, you just require that the pairs do not repeat horizontally, am I right ? You also don't need to exclude circular pairs (seeing the latin square as a cylinder or a torus) ?
