Dear René,
The theorem whose proof I am trying to formalize is surjection iff right
cancellable <https://proofwiki.org/wiki/Surjection_iff_Right_Cancellable>.
Specifically, sufficient condition
<https://proofwiki.org/wiki/Surjection_iff_Right_Cancellable#Sufficient_Condition>
which uses the definition right cancellable mapping
<https://proofwiki.org/wiki/Definition:Right_Cancellable_Mapping>.
Best, Abel
