Hello,

I was just looking for a predicate version of Relation.Image, but could
not find one, while most other definitions are available for both. Is
that a deliberate mission?

Greetings,

Hi Joachim,

I do not thing that omission is deliberate. You will find more missing
twins.

Generally, the relation material in HOL-Main stems from very different
Isabelle epochs could profit from some consolidation (uniform naming
conventions etc.) .
