Abstract:
A Gray code of size $n$ is a cyclic sequence of all binary words of length $n$ such that two consecutive words differ exactly in one position. We say that the Gray code is a distance code if the Hamming distance between words located at distance $k$ from each other is equal to $d$. The distance property generalizes the familiar concepts of a locally balanced Gray code. We prove that there are no distance Gray codes with $d=1$ for $k>1$. Some examples of constructing distance Gray codes are given. For one infinite series of parameters, it is proved that there are no distance Gray codes. Tab. 5, bibliogr. 9.
Keywords:
$n$-cube, Hamiltonian cycle, Gray code, uniform Gray code, antipodal Gray code.
