A Few More Cyclic Steiner 2-Designs
In this paper, we prove the existence of a cyclic (v, 4, 1)-BIBD for v = 12t + 4, 3 t 50 using computer programs, which are useful in recursive constructions for cyclic designs....

Classes of optical orthogonal codes from arcs in root subspaces
We present new constructions for (n, w, ) optical orthogonal codes (OOC) using techniques from finite projective geometry. In one case codewords correspond to (q - 1)-arcs contain...

Optimal (v, 4, 2, 1) optical orthogonal codes with small parameters
Optimal (v, 4, 2, 1) optical orthogonal codes (OOC) with v <= 75 and v = 71 are classified up to equivalence. One (v, 4, 2, 1) OOC is presented for all v 181, for which an opt...
