The Golay code is thus an error-correcting code. It was originally published in with Marcel Golay’s half-page paper, “Notes on Digital Coding”. Today, this .

Golay Code

The Golay code is thus an error-correcting code. These 12 vectors serve as a basis for the code words. Up to four noets can be detected and up to three errors can botes corrected. Any integer from 0 to is within distance three of one of the code words, so that up to three errors can be detected and corrected.

When Voyager visited Saturn and Jupiter, data for the pictures used blocks of Golay code. The bit Golay code is called a semiperfect code.

Add the first bit word that has eight or more differences from all words in the list. The bit Golay code is called a perfect code. The automorphism group is the Mathieu group The code words of weight eight are elements of an 5, 8, 24 Steiner system.

Last to move wins. Start a list with the bit 0 word … Ed Pegg Jr “Golay Code” http: Sloane, Sphere Packings, Lattices, and Groups3rd ed.

The code words are winning positions in the game of Mogul, played with 24 coins in a row. Today, this paper is considered one of the most remarkable papers ever published, with deep, deep connections to group theory, graph theory, number theory, combinatorics, game theory, multidimensional geometry, and even difital physics.

MinT – Golay Code

Repeat, to get the code words. Golay, “Notes on Digital Coding,” Proc. In a notea code word, change those places to 1. Choose 12 polynomial powers with differing initial terms, and append 1 to each polynomial’s coefficient list to obtain a basis for the code words.

Obtain 11 more lists by adding 1 to 11 tomod Details This Demonstration builds the Golay code in four different ways.

Finally, change the bit of each to 1 and gain a basis for the code words. Download free CDF Player. Any integer from 0 to is within distance four of one of the code words.

Modulus 2, one factor of is Consider the powers ofnamely. If an integer is squared modulus 23, the result will not be inthe quadratic nonresidues mod The code words of pn 7 are elements of an 4, 7, 23 Steiner system.

There are polynomials with seven terms.

IRE37, p. Each bit block of data could have up to three errors, and the computers here on Earth could fix these errors. Each turn flips between one and seven rigital such that the leftmost flipped coin goes from heads to tails. The automorphism group is the Mathieu group The only other nontrivial perfect codes are the ternary Golay code and the Hamming code.
