Suppose I am running a $2^2$ factorial design in two blocks. Denote the factors as A and B and the four treatment combinations as $(1), a, b$ and $ab$. Consider the blocking arrangement:
-------------------
| Block1 | Block2 |
|---------|--------|
| (1) | a |
| ab | b |
Now usually we assume that within each block, the treatment combinations are randomly assigned. However, suppose I impose the restriction that instead, within each block, the treatment combinations must be assigned in the order as above (e.g. in Block 1, assign $(1)$ first, then $ab$. Similarly for Block 2). How can this design be analyzed? Does some kind of Order factor need to be considered?
