Abstract
We give a survey on the “method of auxiliary matrices” which constructs from the incidence matrix of a given structure an incidence matrix for a new larger structure by replacing all 0’s resp. l’s in the old matrix by suitable zero matrices resp. “auxiliary matrices”. The method is used in the construction of designs, partial designs, Hjelmslev planes, Klingenberg structures, etc.
