Abstract

It is shown that for any even integer n ≥ 16 and for some b ≥ 1, there exists a skew Room frame of type 2^a^ 4^b^ with n = 2__a__ + 4__b__. As an application, we show that for any integer v ≡ 1,4 (mod 12), there exists a weakly 3‐chromatic linear space with all lines having size 4 iff v > 16. This answers an open problem posed by Colbourn and Rosa. © 1994 John Wiley & Sons, Inc.
