Meaning of delta phi and epsilon symbols to sorority?

In the context of sororities, ΔΦ (Delta Phi) and ε (epsilon) are not standard or widely recognized symbols. Sororities use Greek letters as their names and in their symbols, but there's no established meaning for ΔΦ or ε specifically within the sorority system. They might be used informally within a specific chapter or group for internal purposes, but they wouldn't have a universal meaning across all sororities.
