Talk:Green's relations

From Wikipedia, the free encyclopedia

I was just trying to find an example of a semigroup in which all subgroups are trivial, but there exists an H-class containing more than one element..

Are you sure of yours L-class and R-class in the example? I think they are inverted... (Chaos140 (talk) 08:15, 11 February 2008 (UTC))

[edit] Satoh ... result

How does the result that there are 1,843,120,128 non-equivalent semigroups of order 8 not contradict an earlier assertion in Semi-groups that every monoid G can be embedded in the space of functions G^G ? At most there can be 9^9 semi-groups of order 8. —Preceding unsigned comment added by 92.50.71.112 (talk) 14:23, 14 April 2008 (UTC)
