the difference between a subset and a proper subset
Since ASCII ⊊ unicode, I don't know if there are ASCII codes for subset and proper subset. There are Unicode characters for subset and proper subset though: Subset: ⊂, &sub;, &#8834; Subset (or equal): ⊆, &sube;, &#8838; Proper subset: ⊊, &#8842;,
Because every set is a subset of itself. A proper subset cannot, however, be a proper subset of itself.
