We have the following indirect implication of form equivalence classes:
			
| Implication | Reference | 
|---|---|
| 189 \(\Rightarrow\) 0 | 
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement | 
|---|---|
| 189: | \(EI\ Ab\): For every Abelian group \(A\) there is an injective Abelian group \(G\) and a one to one homomorphism from \(A\) into \(G\).  | 
					
| 0: | \(0 = 0\). |
