## Suslin number vs cellularity

The text currently states *The Suslin number of a topological space X is the minimum cardinal number κ such that every pairwise disjoint family of open subsets of X has cardinality less than κ: cf. Cardinal characteristic. This is closely related to the cellularity: the supremum of the cardinalities of pairwise disjoint families of open subsets.* Yet the article Cardinal characteristic states that *The Suslin number of a space is also called its cellularity* and this is supported by modern references. It also seems to be what the text is saying. What is the difference, if any? Richard Pinch (talk) 20:07, 19 December 2015 (CET)
