Correction to
On the Asymptotic Existence of Complex Hadamard Matrices,
by R. Craigen, W. H. Holzmann, H. Kharaghani,
J. Combin. Des., 5:5, (1997), 319--327: In Corollary 4.2 page 325 the number
969 should be 959, as also hinted at by the comment immediately following
the corollary.
Correction to
Complex Golay sequences: structure and applications,
by R. Craigen, W. H. Holzmann, H. Kharaghani,
Discrete Math., 252:1-3, (2002), 73--89: On page 85, point 1. wherein is a
long list of 159 values for p. This list should have 160 values, namely, it should also have the number 477 (between 475 and 499 in the list).
Correction to
Weak Amicable T-Matrices and Plotkin Arrays,
by W. H. Holzmann, H. Kharaghani, J. Combin. Des., 16:1, (2008), 44--52: In Example 4 page 47 the last plus sign should be a minus sign, so the last equation should be identical to the equation on line 13 located mid-page above it.
Supplements and corrections:The excess problem and some excess inequivalent matrices of order 32,
by W. H. Holzmann, H. Kharaghani, M. T. Lavassani,

Figures and images to accompany the paper
On the Plotkin Arrays, by W. H. Holzmann
and H. Kharaghani, Austral. J. Comb., 22 (2000), pp. 287-299.
There is a typo in Theorem 5 (The First Multiplication Theorem),
at the bottom of page 289. An ``8'' was omitted:
OD(mt;ts1,...) should read OD(8mt;ts1,...).

From the paper A computer search for complex Golay sequences, by
W. H. Holzmann, H. Kharaghani, Australas. J. Combin., 10, (1994), 251--258,
these are the first examples of Complex Golay sequences of order 11 and 13, which also happen to be the only ones up to equivalence:
