Conclusion

1. is finite[T](LET (v0:(vert(G!1)) ) = choose[T](vert(G!1)) IN
{n:T | vert(G!1)(n) AND (n /= v0) AND edge?[T](G!1)(v0, n)})

Tactic
 CASE "subset?({n: T | vert(G!1)(n) AND
n /= choose[T](vert(G!1)) AND
edge?[T](G!1)(choose[T](vert(G!1)), n)},vert(G!1))"
Premise 1.   (has proof of 3 steps)
