- a= number of vertex links homeomorphic to the sphere
- b= number of vertex links homeomorphic to the real projective plane
- c= number of vertex links homeomorphic to the torus
- d= number of vertex links homeomorphic to the Klein bottle
- e= number of vertex links homeomorphic to the genus three nonorientable surface

- g= number of vertex links homeomorphic to the genus five nonorientable surface

- a - For any subcomplex Δ' of Δ, g
_{2}(Δ) ≥ g_{2}(Δ'). Usually v is a vertex and Δ'=st(v), so g_{2}(Δ) ≥ g_{2}(st v) = g_{2}(link v). - b - If n is the number of singular vertices, then g
_{2}≥ 2 χ - ( n-3 choose 3). If n-3 < 3, then the binomial coefficient is interepreted as zero. - c - If Δ has 8 singular vertices and m of them are Klein bottles, then g
_{2}≥ 2 χ - 10 + (m/3) - d - If Δ has 8 singular vertices and any of them are real projective planes, then g
_{2}≥ 2 χ - 7 - e - If Δ has 8 singular vertices including 3 projective planes and 2 Klein bottles, then g
_{2}≥ 2 χ - 5

Except where otherwise noted, the f-vectors are characterized through h- and g-vectors by, h_{0}=1, h_{4}=1-χ, h_{3} - h_{1} = 2 χ, h_{1} ≥ f_{0}-4, and Γ ≤ g_{2} ≤ (g_{1} +1 choose 2), where f_{0} is the minimum number of vertices required for a complex with the given singularities.

- The first entry is the minimum number of vertices possible for the given singularities
