Summary
In semigroup theory, the notion of semiband which generalises that of band, may play an interesting role both in pure algebraic theory and in computing and programming theory.
A relatively complete study of the structure of semiband of type two is given together with a complete listing of their isomorphism class.
We are much indebted to G.J. Lallement for suggesting improvements in our presentation and for communicating his computations concerning semibands of type two.
