摘要
A table of upper bounds for K3,2(n1, n2; R), the minimum number of codewords in a covering code with n1 ternary coordinates, n2 binary coordinates, and covering radius R, in the range n = n1 + n2 ≤ 13, R ≤ 3, is presented. Explicit constructions of codes are given to prove the new bounds and verify old bounds. These binary/ternary covering codes can be used as systems for the football pool game. The results include a new binary code with covering radius 1 proving K2(13, 1) ≤ 736, and the following upper bound for the football pool problem for 9 matches: K3 (9, 1) ≤ 1356.
