Hi. I'm looking to design an experiment in the following manner.
There are 4 groups with 4 designs in each group.

4 sequences for each subject:
1) within the 4 groups, one of the 4 designs
2) within the 3 other groups, within the 3 designs not picked
3) within the 2 other groups, within the 2 designs not picked
4) what is left.

Any ideas of how I would go about programming this into medialab?
Thanks in advance!
