Situation: I am sitting on an armchair facing the table I am at while there is an armchair that is at the same table as me in my one o'clock direction and another armchair that is at the same table as me in my twelve o'clock direction.
Alternative situations: I sat down at a chair reading a book and to my right was a table. I shuffle a deck of cards at the table and a plant is behind me and to the right.
Question: Can the number of chairs behind me be divided by three?
