    "abstract": "The tree amplitudes in scalar field theories are presented at all $n$. The\nmomentum routing of propagators is given at $n$-point in terms of a specified\nset of numbers, and the mass expansion of the massive theories is generated. A\ngroup structure on the diagrams is given. The tree amplitudes can be used to\nfind the effective action.",
