I'm trying to find the following paper:
R.M. Wilson, “Decomposition of a complete graph into subgraphs isomorphic to a given graph.“ Congressus Numerantium XV (1975), 647-659. MR0396347 (53:214)
Also seen cited as:
R.M. Wilson, “Decomposition of a complete graph into subgraphs isomorphic to a given graph.“ Utilitas Math, Winnipeg (1976)
I cannot find it anywhere, online or offline. How am I supposed to progress here?
