I vaguely remember the gist of an old math puzzle, but I can't recall enough details to recreate it, and it's driving me nuts. Anyone know it?
There is a group of brothers who are dividing up of a herd of animals, according to some rules. The numbers don't work out. Another man comes along, and loans them one of his animals; then the numbers work out with exactly one animal left over, so the man gets his animal back.
If this rings a bell with anyone, I'd be grateful. -- Floquenbeam ( talk) 00:47, 11 September 2011 (UTC)
According to
http://www.jimloy.com/puzz/will.htm , there are *exactly* 7 solutions for 3 sons: (7,1/2,1/4,1/8);(11,1/2,1/4,1/6);(11,1/2,1/3,1/12);(17,1/2,1/3,1/9);(19,1/2,1/4,1/5);(23,1/2,1/3,1/8);(41,1/2,1/3,1/7)

Is e1×e[(−x÷2)+(x2÷3)+···]=e[1−(x÷2)+(x2÷3)+···];where 'e' is the exponential function ?```` — Preceding unsigned comment added by Smprince055 ( talk • contribs) 15:19, 11 September 2011 (UTC)
I want have all possible 2x2x2-tensors over ℤ2 listed with its ranks. -- 84.62.194.162 ( talk) 17:44, 11 September 2011 (UTC)
