Let us denote by COILS(v) a (3, 2, 1)-conjugate orthogonal idempotent Latin square of order v, and by ICOILS(v, n) an incomplete COILS(v) missing a sub-COILS(n). We shall investigate the existence of ICOILS(v, n). The construction of an ICOILS(8, 2) has already been instrumental in the construction
We show that any partial 3r Γ3r Latin square whose filled cells lie in two disjoint r Γr sub-squares can be completed. We do this by proving the more general result that any partial 3r by 3r Latin square, with filled cells in the top left 2r Γ 2r square, for which there is a pairing of the columns s
## Abstract In this paper, it is shown that a latin square of order __n__ with __n__ββ₯β3 and __n__ββ β6 can be embedded in a latin square of order __n__^2^ which has an orthogonal mate. A similar result for idempotent latin squares is also presented. Β© 2005 Wiley Periodicals, Inc. J Combin Designs 1
Let us denote by COILS(v) a (3,2, l)-conjugate orthogonal idempotent Latin square of order v, and by ICOILS(v, n) an incomplete COILS(v) missing a sub-COILS(n). A necessary condition for the existence of an ICOILS(v, and the necessary condition for its existence has recently been shown by the auth
