Examples

“Bitetrads are found in Piptadeniopsis (Fig. 10), Micro-lobius (Fig. 9) and in any species of Mimosa(Fig. 4) and Piptadenia, but tetrads and/or polyads are present in the same taxa too.”

“These works revealed that Mimosa pollen grains canbe grouped into tetrads, bitetrads (eight grains) or polyads (12 or 16 grains).”

“Two tetrads are also assumed to join base to base producing the bitetrad, and from these two forms the tetrad and the bitetrad, all the atoms and molecules of our planet are supposed to be produced.”

“Single tetrads, whenever they ar not permitted to cohere in larget numbers, will in every case cohere as bitetrads. Are we, then, to look for the bitetrad among chemical elements?”

“To achieve this, one has to pay a relatively high price, namely to increase the number of degrees of freedom, replacing the tetrad field by the bitetrad field.”
