[ 1 ] - Some properties of a class of polyhedral semigroups based upon the subword reversing method

In this paper a certain class of polyhedral semigroups which has a presentation $$ is examined‎. ‎The completeness of the presentation and solvability of word problem of this class of semigroups is determined‎. ‎Moreover the combinatorial distance between two words is determined‎.
