Re: [math-fun] combinatori(c)al

<< Which of the spellings is correct/usual, the one with or without the 'c'? At least in the U.S., one sees only "combinatorial" -- without the "c". P.S. A small request -- could you please sign your math-fun messages with your name, at least your first name? It would seem more friendly this way. Regards, Dan Asimov
