**Abstract.** A straightforward proposal for a group-theoretic
invariant of knots fails if one really means groups, but works once
generalized to meta-groups (to be defined). We will construct one
complicated but elementary meta-group as a meta-bicrossed-product (to be
defined), and explain how the resulting invariant is a not-yet-understood
generalization of the Alexander polynomial, while at the same time
being a specialization of a somewhat-understood "universal finite type
invariant of w-knots" and of an elusive "universal finite type invariant
of v-knots".
