Firstly, thank you very much for the links to existing graph invariant databases! I only knew about ISGCI.
Regarding my question, I suppose I'll just accept that this invariant currently has no name. I can always add the invariant once a name eventually catches on.
My database is currently ... (more) |

Name for a graph invariant: minimal positive integer $d$ such that the graph is $d$-biclique-free Consider this: > A class of graphs $C$ is said to be $d$-biclique-free, for some $d > 0$, if $K{d,d}$ is not a subgraph of any $G \in C$ Source: https://arxiv.org/abs/1502.04803 Seems like the definition implies a graph invariant, the minimum $d$ for which a graph is $d$-biclique-free. I... (more) |

Classification for involutory real infinite series Out of curiosity I'm playing around with the concept of involutory functions. An involutory function (involution) is a function whose composition with itself is the identity function (i.e. ${f \circ f} = id$). In other words, involutions are functions that are their own inverses (i.e. $f = f^{-1}... (more) |
