I think the unit tests are wrong. In particular lottery(12,11)=66 not 6.
Great catch! That one is now fixed. That happened when I was copying the results of the array of values from 1-12 for lottery(12,x). I guess the values for 11 and 12 were on the next line, and I accidentally deleted one of the 6s in 66 for lottery(12,11). I'll double check the rest of them when I get back on my machine that has MATLAB on it. I'm rescoring now.
