• It will probably help if you explain what the operator you seek means. Jun 21 '13 at 2:06
• Where did you encounter this? It sounds like a congruence symbol... Jun 21 '13 at 2:08

$\cong$, perhaps? Your question is very hard to understand. $\propto$ is a different symbol that relates to proportionality….
• It tends to mean that two things are isomorphic in some sense. For example, in geometry it means they are congruent. What it means in the context of $\frac{\text{text}}{\text{text}} \cong \frac {\text{text}}{\text{text}}$, I haven't the foggiest. Jun 21 '13 at 4:10
