  A delta-move is a local move on a link diagram. The delta-Gordian distance
between links measures the minimum number of delta-moves needed to move between
link diagrams. A self delta-move only involves a single component of a link
whereas a mixed delta-move involves multiple (2 or 3) components. We prove that
two links are mixed delta-equivalent precisely when they have the same pairwise
linking number and same components; we also give a number of results on how
(mixed/self) delta-moves relate to classical link invariants including the Arf
invariant and crossing number. This allows us to produce a graph showing links
related by a self delta-move for algebraically split links with up to
9-crossings. For these links we also introduce and calculate the
delta-splitting number and mixed delta-splitting number, that is, the minimum
number of delta-moves needed to separate the components of the link.
