I am failing to remember where I have seen /\ and \/ used in the wild.

CPL's typeset descriptions have big mathematical conjunction and
disjunction operators. But I don't think I heard of composing them

1960s BCPL manuals have a similar typographic convention to ALGOL 60.

The ALGOL 68 revised report defines all three of ∨| or for the
disjunction operator.
