Abstract
A universal cycle is a compact listing of a class of combinatorial objects. In
this paper, we prove the existence of universal cycles of classes of labeled graphs...

proof.
Proof of Theorem 2: Suppose that Λ, M ⊆ A are maximal dissociated subsets of
A. By maximality of Λ, every element of A, and consequently every element of M, is a
linear combination of ... the element of M, and therefore every maximal dissociated
subset of A is a singleton, too ) , we assume |M| ≥ 2 below.
Since every element of Λ is a linear combination of the e...
