heal.abstract	We give two new circlulant D-optimal designs of order 118, which are of Ehlich's type. We note this is the first time that a D-optimal has been constructed for order 118 = 2 (.) 59. As a consequence new skew-Hadamard matrices of order 236 = 4 (.) 59 are also constructed for the first time. (C) 2004 Elsevier B.V.. All rights reserved.	en
