  We construct all codimension 1 multi-germs of maps (k^n,T)-->(k^p,0) with n >
p-2, (n,p) nice dimensions, k = R or C, by augmentation and concetenation
operations, starting from mon-germs (|T|=1). As an application, we prove
general results for multi-germs of corank <2: every one has a real form with
real perturbation carrying the vanishing homology of the complexification,
every one is quasihomogeneous, and when n=p-1 every one has image Milnor number
equal to 1 (the comparable result for n>p-1 being already known).
