Definition

A group $G$ is termed a Lazard Lie group if there is a natural number $c$ such that both the following hold:

1. $G$ is uniquely $p$-divisible for all primes $p\leq c$
2. For any three elements of $G$, the subgroup of $G$ generated by these three elements is a nilpotent group of nilpotency class at most $c$.

A Lazard Lie group is a group that can participate on the group side of the Lazard correspondence. The Lie ring on the other side is its Lazard Lie ring.

p-group version

A p-group is termed a Lazard Lie group if every subgroup of it generated by three elements, has nilpotency class at most $p-1$ where $p$ is the prime associated with the group.

Facts

Lazard's theorem gives a method to construct a Lazard Lie ring for any Lazard Lie group. This construction and its paraphernalia go under the name of the Lazard correspondence.

3-local

A group occurs as a Lazard Lie group if and only if, for any three elements of the group, the subgroup they generate occurs as a Lazard Lie group. For full proof, refer: Lazard Lie property is 3-local
