Given n and m unsigned integral types, will the expression
(n & m) <= m always be true ?

Natural Numbers (N), (also called positive integers, counting numbers, or natural numbers); They are the numbers {1, 2, 3, 4, 5, …}
Hence, O((n+1)!) is not the same as O(n!) . As noted by Nils Pipenbrinck, in practice it doesn't matter, as both classes of problems are not tractable for practical values of n .
n refers to the size of the input, in your case it's the number of items in your list. O(n) means that your algorithm will take on the order of n operations to insert an item. e.g. looping through the list once (or a constant number of times such as twice or only looping through half).
} O(n) represents the complexity of a function that increases linearly and in direct proportion to the number of inputs. This is a good example of how Big O Notation describes the worst case scenario as the function could return the true after reading the first element or false after reading all n elements.
Yes, it is true.
It should be readily apparent that a necessary condition for y > x is that at least one bit position is set to 1 in y but 0 in x. As & cannot set a bit to 1 if the corresponding operand bits were not already 1, the result cannot be larger than the operands.
