%N List of impossible triples {V, F, E} that satisfy Euler's equation V=E-F+2 but do not correspond to polyhedra.
%C This set of triples seems to be a finite set of "graphs" that are Euler solutions but not polyhedra.
%F If V<4 and F<4 and E<7 and V=E-F+2: a(n) = {V(m),F(m),E(m)}
%t a = Delete[Union[Flatten[Table[If[v + f - 2 - e0 == 0, {v, f, e0}, {}], {v, 0, 3}, {f, 0, 3}, {e0, 0, 6}], 2]], 1]; Flatten[a]
