The a(0) = 1 through a(4) = 19 loop-graph edge sets (loops shown as singletons):
{} {{1}} {{1,2}} {{1},{2,3}} {{1,2},{3,4}}
{{1},{2}} {{1,2},{1,3}} {{1},{2},{3,4}}
{{1},{1,2}} {{1},{2},{3}} {{1},{1,2},{3,4}}
{{1},{2},{1,3}} {{1},{2,3},{2,4}}
{{1},{1,2},{1,3}} {{1},{2},{3},{4}}
{{1},{1,2},{2,3}} {{1,2},{1,3},{1,4}}
{{1,2},{1,3},{2,3}} {{1,2},{1,3},{2,4}}
{{1},{2},{3},{1,4}}
{{1},{2},{1,2},{3,4}}
{{1},{2},{1,3},{1,4}}
{{1},{2},{1,3},{2,4}}
{{1},{2},{1,3},{3,4}}
{{1},{1,2},{1,3},{1,4}}
{{1},{1,2},{1,3},{2,4}}
{{1},{1,2},{2,3},{2,4}}
{{1},{1,2},{2,3},{3,4}}
{{1},{2,3},{2,4},{3,4}}
{{1,2},{1,3},{1,4},{2,3}}
{{1,2},{1,3},{2,4},{3,4}}
