Abstract
It has previously been shown that there is a unique set Π of primal graphs such that every graph has an edge-decomposition into non-isomorphic elements of Π and that the only decomposition of an element of Π into non-isomorphic elements of Π is the obvious one. Here it is shown that there are infinitely many elements of Π even among graphs having a relatively simple structure. On the other hand, within this same class of graphs, we show that 'most' of them are not primal.
