Conjecture   For any funcoid $ f $ and reloid $ g $ having the same source and destination \[ ( \mathsf{\tmop{RLD}})_{\tmop{out}} f \subseteq g \subseteq (    \mathsf{\tmop{RLD}})_{\tmop{in}} f \Leftrightarrow ( \mathsf{\tmop{FCD}}) g    = f. \]

See Algebraic General Topology for definitions of used concepts.

Counter-example: $ f=(=)|_{\Omega} $ where $ \Omega $ is the Frechet filter, $ g=\emptyset $. Then $ (\mathsf{\tmop{RLD}})_{\tmop{out}} f=\emptyset $.
