Let \( a_{1}, a_{2}, a_{3}, a_{4} \) be 4 distinct numbers chosen from \( 1, 2, \cdots, 100 \) that satisfy
\[ \left(a_{1}^{2}+a_{2}^{2}+a_{3}^{2}\right)\left(a_{2}^{2}+a_{3}^{2}+a_{4}^{2}\right)=\left(a_{1}a_{2}+a_{2}a_{3}+a_{3}a_{4}\right)^{2}. \]

How many such ordered arrays \( \left(a_{1}, a_{2}, a_{3}, a_{4}\right) \) exist?
