Hello
There is no way to block ONLY this networks with 2 access-lists statements.
With overlaping networks you could write your access-list with one line (but
it'll overlap 16384 networks) :
permit 104.0.0.0 23.59.55.0 - if my manual calculatioms are correct :)
or with two (summarizing 1st add with 3rd and 2nd with 4th) :
permit 112.2.1.0 3.41.50.0
permit 111.16.6.0 16.8.0.0
there is a nice acces-list white paper on internetworkexpert site
