How to obtain all states of n checkboxes to a List<List<bool>>, For example 5 checkboxes have 2^5 states, then convert this number (32) to its binary values in a list and finaly convert these binaries to a List<List<bool>>  

[ 0b11111, 0b11110, 0b11100, ... ] => { {true,true,true,true,true}, {true,true,true,true,false}, {true,true,true,false,false}, ... }

Use the shift operator.  I don't see any reason to convert to a List<bool> then a binary as the checkbox list is already a collection of I/O.

Is it a way to obtain all of the alternations (combinations) of n bits in a List<List<bool>>?

This is a math question? A 5-bit number is 2^5 = 32.    I think you are asking about factorials but I'm not sure.  Anyway 32! = 2.6313083693369353016721801216 x 10^35.  And a  very large number.
