0.15.4
This is a minor release that fixes a few bugs.
In previous versions, the homomorphism-finding tools sometimes returned purported ‘monomoprhisms’ that were not injective. This problem was reported by Gordon Royle, see Issue #222, and fixed by James D. Mitchell in PR #223. In addition, Wilf A. Wilson fixed a bug in DigraphNrEdges
. This function could previously lead to a crash when given a digraph whose OutNeighbours
contained entries not in IsPlistRep
.
