I mailed the author a few days ago, but haven't heard back.
Can anybody interpret the cryptic descriptions in a way that would 
explain why (e.g.) 28 is in A160251?
Does "number of angles" refer to something else than "number of 
vertices" = "number of edges"?
However, since the complement (A160259) even mentions Gauss's theorem, 
this sounds unlikely ...
