In abstract algebra, the group isomorphism problem is the decision problem of determining whether two group presentations present isomorphic groups.
The isomorphism problem was identified by Max Dehn in 1911 as one of three fundamental decision problems in group theory; the other two being the word problem and the conjugacy problem.
