Derivation of Two Associate PBIBD from Necessary Properties of BIBD

One of the main shortfall Balanced Incomplete Block Designs is that design not available for all parameter sets. Thus, some sets satisfy necessary conditions BIBD cannot be constructed as such. This means designs possible to with a single association scheme (λ). Given structural difference exist between and PBIBD later do have but rather m schemes, study believed if could associations then maybe broken down more than one in form such might using other methods PBIBDs. The aimed at determining whether two PBIBDs derived from properties BIBDs. reason maiking transformation been determined meaning λ. Therefore, felt into 2 (λ1 λ2) PBIBD. related Using properties, created eight linear equations Gauss Jordan Elimination method, was able solve unknown parameters scheme. end convert
