#5415: wrong definition of multifactorial?
------------------------------+---------------------------------------------
Reporter: cwitty | Owner: robertwb
Type: defect | Status: new
Priority: major | Milestone: sage-3.4
Component: basic arithmetic | Keywords:
------------------------------+---------------------------------------------
The multifactorial method on integers is different than the one at
http://mathworld.wolfram.com/Multifactorial.html and
http://www.research.att.com/~njas/sequences/A007661; unless there are
multiple competing definitions of multifactorial, this is a bug.
(The references give, for example, (5).multifactorial(3) == 10, whereas
Sage currently returns 5.)
