Hi Researcher101,

» Dear All, I wanna know what exactly the randomization sequences if I will go for fully replicate ( Four periods) with three arms/treatments ( T1, T2, R)

You need four sequences; in your case

    P1  P2  P3  P4
S1  T1   R  T2   R
S2   R  T1   R  T2
S3  T2   R   R  T1
S4   R  T2  T1   R

For the evaluation exclude either T2 or T1 to obtain two partial replicate designs with missing () observations:

    P1  P2  P3  P4
S1  T1   R   •   R
S2   R  T1   R   •
S3   •   R   R  T1
S4   R   •  T1   R

    P1  P2  P3  P4
S1  •    R  T2   R
S2   R   •   R  T2
S3  T2   R   R   •
S4   R  T2   •   R
