Formula

The laboratory has developed a digital generator capable of producing different variations for each formula from the letters of the alphabet. Since the number of combinations for each formula is infinite, it was decided to limit the atoms to a pattern of constant width and height. That is, the combinations of atoms will not exceed these limits. In addition, just as the letters H and K are made up of two parts, it was decided in the programming process to allow the atoms to produce variations consisting of one or two parts.
