an interesting sequence

Lucas term =L(n)

L(y)-l(x) V L(y) is prime for terms less than 90 (for a y and some x). not sure if it is finite though. i cant seem to find any that are more than that (i do not have any proofs at all, i came across this incidentally).

Well sure, I mean let's say you have a set S of some pairs of real numbers where the first numbers always differ (otherwise, it wouldn't be a function by the 'vertical line test' or whatever you call it). Define f: R → R by f(x) = y if (x, y) is in S and f(x) = 0 otherwise.
