2 The Markov Matrix $M$ resulting from the $n$-cube in
4 cycle is removed, is doubly stochastic
8 The iteration graph issued from the $n$-cube where an Hamiltonian
9 cycle is removed is strongly connected

15 \item To focus on the generation of Hamiltonian cycles in the
16 $n$-cube, \textit{i.e.},
17 \item To find cyclic Gray codes:
18 sequences of $2^n$ codewords ($n$-bits strings)
19 where two successive elements differ in only one bit position and
20 and where the last codeword
21 differs in only one bit position from the first one
