Four treatments were given to 24 experimental units partitioned into 8 blocks of size 3. This means that only three out of four treatments is given in each block, but in such a way that each treatment occurs equally often (6 times) AND such that each pair of treatments "meet" equally often (4 times). The response is Y and the covariate is X.
