Abstract: Wendt's binomial circulant determinant, $ {W_m}$, is the determinant of an m by m circulant matrix of integers, with (i, j)th entry $ \left( {\begin{array}{*{20}{c}} m \\ {\vert i - j\vert} \\ \end{array} } \right)$ whenever 2 divides m but 3 does not. We explain how we found the prime factors of $ {W_m}$ for each even $ m \leq 200$ by implementing a new method for computations in algebraic number fields that uses only modular arithmetic. As a consequence we prove that if p and $ q = mp + 1$ are odd primes, 3 does not divide m, and $ m \leq 200$, then the first case of Fermat's Last Theorem is true for exponent p.
