I have a probability (6P4 and 8P4) ad Latin square (http://statpages.info/latinsq.html) problem.
For a Latin square of 4 digits,
1 2 4 3
2 3 1 4
3 4 2 1
4 1 3 2
each number appear in each ordering position once and precede and follow by each number once.
I would like something similar to be done for 1,2,3,4,5,6
In 6P4, there are 360 combinations, but I need to reduce it to a latin square of 4 digits so only 4 of them can appear in the sequence, so for example, 1 should be precede and followed by null,2,3,4,5,6 only once in each of the 4 number sequence.
I only need the Latin Square answer patterns for 6P4 and 8P4.
Please quote the price and the time required for the job.
