[sage-devel] "All Rights Reserved" in a part of code

[Jori Mäntysalo]

http://sage.sis.uta.fi/documentation/reference/groups/sage/groups/perm_gps/permgroup.html 
contains

"Christopher Swenson (2012): Added a special case to compute the order 
efficiently. (This patch Copyright 2012 Google Inc. All Rights Reserved. 
)"

What is this? A part of code in the core that is not free???
