to note: 1) arttype is numeric. I thought this was the best way of allowing arbitarily large factorials, even though factorial(2^63) is a large number. Happy to change to integers if this is overkill. 2) since we're accepting numeric arguments, the patch tests for floats. If a numeric is passed with non-zero decimal portion, an error is raised since (from memory) they are undefined. Gavin Sherry
