comment Can one prove that toric varieties are Cohen-Macaulay by finding a regular sequence?
I agree with @NeilEpstein: in principle any homological proof that a ring is CM could be translated in an existence proof for a regular sequence.

Thanks a lot. Not only is the math beautiful but Roland's answer and yours do cast an interesting light on the motivating linguistic problem.

comment Average number of distinguished leaves in a binary tree
@TheMaskedAvenger Yes, full means nodes have 0 or 2 children. In particular, an automorphism fixes the root node because it is the only node of degree 2 (or 0 in the case of a single vertex).
