Abstract
In 1985, Chor et al. conjectured that the only 1-resilient symmetric f unctions are the exclusive-or of all n variables and its negation. In this note the existence of symmetric resilient functions is shown to b e equivalent to the existence of a solution to a simultaneous subset s um problem. Then, using arithmetic properties of certain binomial coef ficients, an infinite class of counterexamples to the conjecture is ob tained.
