Simplex - tetratomic fragments of fixed composition, structure, chirality and symmetry
Simplex descriptor - number of identical simplexes in a molecule
Example of 2D simplexes generation for formic acid
Advantages:
We have two implementations of simplex descriptors (they are incompartible with each other)
