Corresponding to each odd integer q, we construct a complex orthogonal design. The number of variables and the form of the design depends on the integer q. Almost all of these designs are new and as a corollary we get a new asymptotic existence result for complex Hadamard matrices.

## Abstract A (Ξ½, __k__, __k__βˆ’1) near resolvable block design (NRBD) is __r__‐rotational over a group __G__ if it admits __G__ as an automorphism group of order (Ξ½βˆ’1)/__r__ fixing exactly one point and acting semiregularly on the others. We give direct and recursive constructions for rotational NR
