Consider I have two sets that neither one is a subset of the other (for example, the set of prime numbers and the set of odd integers). Is there a specific notation that combines the meanings of both ⊄ and ⊅ ?
Also, is there a notation to mean that two sets are completely distinct and share no elements in common (for example, the sets of odd and even integers)?
≠ seems very inappropriate, and I'd like to avoid it.
Context: My area is actually Computer Science. I'm using this refine my vocabulary in order to teach my students about subnetting (which is basically about sets and subsets of IP addresses), and to write some exercises for them. I'll probably use the words incomparable and disjoint as suggested.
