β¦ Synopsis
For each nonnegative integer r, we determine a set of graph operations such that all r-regular loopless graphs can be generated from the smallest r-regular loopless graphs by using these operations. We also discuss possible extensions of this result to r-regular graphs of girth at least g, for each ΓΏxed g.

## Abstract For __k__=0, 1, 2, 3, 4, 5, let ${\cal{P}}\_{k}$ be the class of __k__ βedgeβconnected 5βregular planar graphs. In this paper, graph operations are introduced that generate all graphs in each ${\cal{P}}\_{k}$. Β© 2009 Wiley Periodicals, Inc. J Graph Theory 61: 219β240, 2009
## Abstract All planar connected graphs regular of degree four can be generated from the graph of the octahedron, using four operations.
Let G be chosen uniformly at random from the set G G r, n of r-regular graphs w x Ε½ . with vertex set n . We describe polynomial time algorithms that whp i find a Ε½ . Hamilton cycle in G, and ii approximately count the number of Hamilton cycles in G.
If rjn Γ 1 and rn is even, then K n can be expressed as the union of t nΓ1 r edgedisjoint isomorphic r-regular r-connected factors.
