Query: A note on Kneser-Haken finiteness   Kneser-Haken Finiteness asserts that for each compact 3-manifold M there is
an integer c(M) such that any collection of k>c(M) closed, essential, 2-sided
surfaces in M must contain parallel elements. We show here that if M is closed
then twice the number of tetrahedra in a (pseudo)-triangulation of M suffices
for c(M).
