  The McMullen Correspondence gives a linear dependence between M-sequences of
length |d/2|+1 and f-vectors of simplical d-polytopes. Denote the transfer
matrix between g and f by M_d. Recently, Bjorner proved that any 2x2-minor of
M_d is nonnegative and conjectured that the same would be true for arbitrary
minors. In this paper we answer the question in the affirmative.
