Abstract: A pair {T0,T1} of disjoint collections of k-subsets (blocks) of a set V of cardinality v is called a t-(v,k) trade or simply a t-trade if every t-subset of V is included in the same number of blocks of T0 and T1. The cardinality of T0 is called the volume of the trade. Using the weight distribution of the Reed--Muller code, we prove the conjecture that for every i from 2 to t, there are no t-trades of volume greater than 2^{t+1}-2^i and less than 2^{t+1}-2^{i-1} and derive restrictions on the t-trade volumes that are less than 2^{t+1}+2^{t-1}.
