β¦ Synopsis
Let m = 2k. We show that for some 0 β€ < 1, a partial directed m-cycle system of order n can be embedded in a directed m-cycle system of order (mn)/2 + (2m 2 + 1) (8n + 1)/4 + 4m 3 2 + 4m + 1/2. For fixed m, this is asymptotic in n to (mn)/2 and so for large n is roughly one-fourth the best known bound of 2mn + 1.

We prove that if m is odd then a partial m-cycle system on n vertices can be embedded in an m-cycle system on at most m((m -2)n(n -1) + 2n + 1) vertices and that a partial weak Steiner m-cycle system on n vertices can be embedded in an m-cycle system on m(2n + 1) vertices.
Recent results have found small embeddings for partial m-cycle systems of order It with A = 1. However, if A> 1 then the best knswn techniques produce embeddings that are often quadratic functions of both m and n a d linear fmctions of A. In this article we obtain embeddings for partial m-cycle syst
## Abstract For odd __m__, relatively little is known about embedding partial __m__βcycle systems into __m__βcycle systems of small orders not congruent to **1** or __m__ modulo 2__m__. In this paper we prove that any partial __m__βcycle system of order __u__ can be embedded in an __m__βcycle syste
## Abstract A wellβknown, and unresolved, conjecture states that every partial Steiner triple system of order __u__ can be embedded in a Steiner triple system of order Ο for all Ο ββ‘ 1 or 3, (mod 6), Ο ββ₯β2uβ+β1. However, some partial Steiner triple systems of order __u__ can be embedded in Steiner t
