Let Σ be the four letter alphabet a,b,c,d. We give an example of a uniformly growing endo-morphism g:Σ.→Σ.; with ¦g(a)¦=85; such that the iteration of g yields an a

We show even with respect to very flexible reductions that NP cannot have sparse hard sets unless P = NP; an immediate consequence of our results is: If any NP-complete set conjunctively reduces to a sparse set, then P = NP. We also show that any set . that reduces to some sparse set
