*****************************************
In http://www.cs.nyu.edu/pipermail/fom/2012-January/016155.html I wrote
f,g commute (f is g commuting) if and only if fog and gof agree on
dom(f) intersect rng(f).
This should read
f,g commute (f is g commuting) if and only if the two functions fog
and gof agree where both functions are defined.
Also, add:
A graph on Q[0,k]^n is order invariant if and only if its adjacency
relation is order invariant as a subset of the ambient space Q[0,k]^2n.
