Edmond W. H. Lee, Jian Rong Li · Dissertationes Mathematicae · 2011
Two semigroups are said to be {\it distinct} if they are neither isomorphic nor anti-isomorphic. Although there exist 1373 distinct monoids of order six, only two are known to be non-finitely based. In the present dissertation, the finite basis property o
