Abstract
Recently, Type IV self-dual codes over the ring double-struck F sign 2 + udouble-struck F sign 2 of order 4 have been introduced. In this correspondence, we construct five optimal Type IV self-dual codes which are the first examples of such codes for that length. We also give several new optimal Type IV self-dual codes, and Type IV self-dual codes which improve the upper bounds for minimum weights.
