It is shown that production amplitudes are necessary in two-particle scattering with any isotopic spins. The proof assumes that the amplitudes satisfy the analyticity requirements of Mandelstam representation with a tinite number of subtractions and the result is based on the interconnection between

We continue the investigation of a combinatorial problem concerning multisets of equivalence relations on a finite set. ## 1999 Academic Press We denote the least such d by $(r, n). It is easy to see [2] that $(r, 2)=2 r&2 when r is even, while $(r, 2) is undefined when r is odd. Some other values
