> Why does the Complement function reverse lists under some circumstances? It sorts lists into a canonical order (aka "standard order"). See the description of Complement on page 607 and the description of Order on page 660. "Canonical order has several properties. Smaller numbers of a particular type come first. Symbols are ordered lexicographically according to the textual names. Strings are ordered lexicographically. Shorted expressions come first." -- David Jacobson
