Peter Knippertz,Jan-Berend W. Stuut.. = {.., .., …, ..} of .., having the properties for all 1 ≤ . ≤ ., (1) |..| = |..| and (2) the subgraph .[..] induced by .. is isomorphic to the subgraph .[..] induced by ... In this note we generalize this concept, first introduced in 1979 by Chung et al. in Congr Numer 23:3–18, 1979.
