Assume I want to answer a finite question about some infinite structure that can be represented using finite data. As a contrived example: Consider the graph that has as its vertices the natural numbers and an edge (i,j) whenever i divides j. Is there an elegant (lazy evaluation) way to represent this? For instance I could think of a function that investigates the sizes of connected components below the first 500 primes or such.ThomasTue, 21 Feb 2012 02:46:11 -0600http://ask.sagemath.org/question/8728/
