SUMMARY
This discussion focuses on the relationship between modular arithmetic and odd prime numbers, specifically addressing the condition where an odd prime \( p \) divides \( b^2 + 1 \). It establishes that if \( p \) divides \( b^2 + 1 \), then \( p \equiv 1 \mod 4 \). The participants also highlight that the order of \( b \) is 4 modulo \( p \), reinforcing the connection between even numbers and their squares in modular contexts.
