I added the remark that the name "nullity" is rarely used for the cycle rank, based on a Google search in which about 95% of about 25 hits referred to the adjacency nullity. Also based on my experience reading graph theory papers. The reason for adding the remark is to help novices know what is the best terminology to use. Zaslav ( talk) 19:47, 22 August 2016 (UTC) reply
