Note that type casts in the + binary comprehension must either be both present or absent + and that there are no untyped variants for single-type + comprehension as Coq parsing confuses [x | P] and [E | x]. + minset p A == A is a minimal set satisfying p. + maxset p A == A is a maximal set satisfying p. + We also provide notations A :=: B, A :<>: B, A :==: B, A :!=: B, A :=P: B + that specialize A = B, A <> B, A == B, etc., to {set _}. This is useful + for subtypes of {set T}, such as {group T}, that coerce to {set T}. + We give many lemmas on these operations, on card, and on set inclusion. + In addition to the standard suffixes described in ssrbool.v, we associate + the following suffixes to set operations: + 0 -- the empty set, as in in_set0 : (x \in set0) = false. + T -- the full set, as in in_setT : x \in [set: T]. + 1 -- a singleton set, as in in_set1 : (x \in [set a]) = (x == a). + 2 -- an unordered pair, as in + in_set2 : (x \in [set a; b]) = (x == a) || (x == b). + C -- complement, as in setCK : ~: ~: A = A. + I -- intersection, as in setIid : A :&: A = A. + U -- union, as in setUid : A :|: A = A. + D -- difference, as in setDv : A :\: A = set0. + S -- a subset argument, as in + setIS: B \subset C -> A :&: B \subset A :&: C + These suffixes are sometimes preceded with an `s' to distinguish them from + their basic ssrbool interpretation, e.g., + card1 : #|pred1 x| = 1 and cards1 : #| [set x]| = 1 + We also use a trailling `r' to distinguish a right-hand complement from + commutativity, e.g., + setIC : A :&: B = B :&: A and setICr : A :&: ~: A = set0. +</div> +<div class="code"> + +<br/> +<span
