The Editor-in-Chief has retracted this article at the request of the author. After the publication of this article, the author found an error in the proof of Theorem 2.1. The starting point of the proof is the construction of a non-simple t-design from a simple t-design. The proof is incomplete, because it is carried out by only a subset of blocks, and the claim is only valid if the simple design is also a trivial design. As a result, the argument presented does not support the statement in Theorem 2.1, on which the subsequent results are based. As this was one of the key findings of this article, the author considers that the conclusions of this work are unsupported.
