the oncidium is a philadelphus.
sent1: there exists something such that it is a philadelphus. sent2: something is not fitter. sent3: if something does not damascene it is not a philadelphus. sent4: the oncidium is a philadelphus if the grader does damascene. sent5: the grader damascenes if there is something such that it does cover indestructibility and it is not a fitter.
the fact that the oncidium is not a kind of a philadelphus is correct.
sent3 -> int1: that if the oncidium is not damascene then that the oncidium is not a philadelphus hold hold.;
