Editing Cyclomatic number (section)

===Computational chemistry===
In the fields of [[chemistry]] and [[cheminformatics]], the cyclomatic number of a [[molecular graph]] (the number of [[ring (chemistry)|rings]] in the [[smallest set of smallest rings]]) is sometimes referred to as the '''Frèrejacque number'''.<ref>{{citation|last1=May|first1=John W.|last2=Steinbeck|first2=Christoph|title=Efficient ring perception for the Chemistry Development Kit|journal=[[Journal of Cheminformatics]]|volume=6|issue=3|year=2014|page=3 |doi=10.1186/1758-2946-6-3|pmid=24479757|pmc=3922685 |doi-access=free }}</ref><ref>{{citation|last1=Downs|first1=G.M.|last2=Gillet|first2=V.J.|last3=Holliday|first3=J.D.|last4=Lynch|first4=M.F.|year=1989|title=A review of ''Ring Perception Algorithms for Chemical Graphs''|journal=[[J.
