Abstract: G-decomposition of λKv into graphs with seven vertices and seven edges were discussed. First, we gave a recursive structure by holy graph decomposition, and then constructed the graph decompositions wanted in recursive structure using difference method. Finally, we determined the existence spectrum of graph decomposition.

Key words: graph decomposition, holy graph decomposition, difference method
