An independent set with 108 vertices in the strong product of four 7-cycles (C 7 C 7 C 7 C 7 ) is given. This improves the best known lower bound for the Shannon capacity of the graph C 7 which is the zero-error capacity of the corresponding noisy channel. The search was done by a computer program u
