In this paper, we enumeratesuperspecialhyperelliptic curves of genus 4 over finite fieldsfor smallq. This complements our preceding results in the non-hyperelliptic case. We give a feasible algorithm to enumerate superspecial hyperelliptic curves of genusgoverin the case thatqandare coprime and. We executed the algorithm for,,and (4, 19) with our implementation on a computer algebra system Magma. Moreover, we found manymaximalhyperelliptic curves and someminimalhyperelliptic curves overfrom among enumerated superspecial curves.
