  We report on a search for CAZAC sequences by using nonlinear sum of squares
optimization. Up to equivalence, we found all length 7 CAZAC sequences. We
obtained evidence suggesting there are finitely many length 10 CAZAC sequences
with a total of 3040 sequences. Last, we compute longer sequences and compare
their aperiodic autocorrelation properties to known sequences. The code and
results of this search are publicly available through GitHub.
