But it will be significantly harder to find another mnemonic > with a Q. :) I actually owe that one to Chris Smith (see issue 1552). We need to add a U function. That gives us at least QUNICE SO (http://wordsmith.org/anagram/anagram.cgi?anagram=cosinequ&t=1000&a=n ). :-) By the way, whenever I get around to it (like when I am finished with this ODE stuff), I will send in a patch adding Q to the gotchas.txt file. I didn't know about the Q addition.
