Okay, I know there are a certain number of mathematicians who enjoy crosswords. There were a few of us at Yale who’d collaborate, or compare notes if we preferred working them ourselves (holla if ya hear me). Occasionally there’d be a “math” hint, which would throw us off because we’d have to come up with the non-technical answer.
But this one I can’t explain at all:
“Mathematical subgroup”.. Well, they probably mean “group” as “collection”, rather than group. But what is the layman’s meaning for “coset”? They can’t possibly mean the technical sense, because a coset isn’t a subgroup, unless it’s the trivial coset. A coset is an element of the quotient group, and usually isn’t even a group at all!
So what was Mark Milhet thinking? Does anybody know the guy? If so, point him here so he can explain hisself!
