A problem

A quasigroup is a finite set with a binary operation satisfying the cancellation laws; that is, one whose Cayley table is a Latin square. A loop is a quasigroup with an identity element. The multiplication group of a quasigroup or loop is the group generated by the left and right translations (which are permutations).

It is known that almost every quasigroup (that is, a proportion tending to 1 as n → ∞) has multiplication group the symmetric group.

Problem: Does the same statement hold for loops?

Old problems are kept here.
