Suppose a balanced incomplete block design satisfies vb and

Suppose a balanced incomplete block design satisfies v=b, and lamda is odd. Show that v cannot be even. use r(k-1) = lamda (v-1) r is the frequency of x, lamda is the index of the design, k is block size, v is number of treatments and b is number of blocks.

Solution

r(k-1) = lamda (v-1)

r ----> f(x)

v -----> number of treatments

b-----> number of blocks

k----> block size
