Good day. I noticed that one cannot make ring connections with numbers of more than 2 digits in a SMILES string.
i.e. valid structures for diphenylmethane are c1ccccc1Cc2ccccc2 and c%84ccccc%84Cc%85ccccc%85 but c%1000ccccc%1000Cc%1001ccccc%1001 is not. The connections just do not happen as intended.
Is there a reason why we are limited to 2 digit ring connections? Is there a way to have this changed? Is there a way to do something like this within the existing framework in a clever manner?
