Glebsky–Rivera Martínez's weak soficity conjecture

A weakly sofic group is a subgroup of a metric ultraproduct of an arbitrary family of finite groups equipped with bi-invariant metrics. Glebsky–Rivera Martínez's weak soficity conjecture. Every group is weakly sofic. The conjecture links weak soficity to the investigation of Herwig and Lascar and broadens the class of finite-group approximation properties considered in the survey. The source gives no resolution here.
