The triangle k core, or k truss has been intoduced by Cohen (NSA Tech. Report 2008) and Zhang and Parthasarathy (ICDE 2012) independently and runs in time, where is the maximum degree and the number of edges.

Definition Triangle Core

The triangle k-core of a simple undirected graph is the inclusion maximal subgraph where each edge is part of at least triangles in .

Definition Triangle Core Number

The triangle core number of an edge is the maximal k such that
