It is not larger than any FIS. There is no fixed number as
cardinality. We simply use oo.

Have you constructed in your head the Binary Tree that only contains
all finite paths? Have you recognized the difference to the Binary
Tree that also contains the infinite paths? Have you obtained what
nodes make up the difference?

(Remember, Cantor's argument works by node/digits only!)
