Everything in the Universe has numeric symmetry with something else. For example, there are 16 types of spiral galaxies and solar systems can have a maximum of 16 planets. Another example is the fact that Helium has 7 naturally occuring isotopes, it requires a combination of 7 amino acids for the construction of biology, and there are 7 possible types of solar systems. Numeric symmetry allows us to make discoveries that would otherwise be impossible. Numeric symmetry is just one of the amazing aspects of the paradigm of science.
